Block Flow allows you
to create a design that can be defined as a unique block for immediate
instantiation into a design and/or be preserved and set aside for future
use. A completed block is optimized using the customary synthesis, simulation
and place-and-route flows, and may or may not include I/Os. Placement
of components within the block and timing are preserved. When creating
a new project in Libero or Designer, select a "Block Design Flow" instead
of a standard flow, after which the block can be published to a repository.
The block can then be instantiated into a design using the conventional
Libero design flow. Libero IDE v7.3 Block Design supports Fusion, IGLOO,
ProASIC3, Axcelerator, and RTAX-S family devices.
SmartGen Enhancements for Fusion
Analog System Builder (ASB)
- Fusion NGMUX macro enhancement: A second clock input
of the NGMUX is now allowed to drive the NGMUX input as well as other
core logic. This enhancement supports the Fusion Analog System use
model of continuously driving the ACM CLK with a slow clock ( < 10
MHZ ) and simultaneously driving the rest of the logic with a switching
fast/slow clock, without using an additional global resource.
- PreScaler On/Off Selection. The Voltage Monitor,
Current Monitor, and Differential Voltage Monitor configuration dialogs
have been updated to provide a option to select between using or bypassing
the prescaler. When the prescaler is selected, a tooltip shows what
prescaler value is being used for the configuration.
SmartTime
- Bottleneck Analysis: A bottleneck is a point in
the design that contributes to multiple failing paths. This new 7.3
feature finds and lists all bottlenecks according to severity and occurrences.
The list has a format similar to the existing "datasheet" report.
- Clock Analysis for Virtual Clocks: In some cases,
paths from one FPGA may sensitize or be sensitized by paths outside
the FPGA (e.g. on the board, or on another FPGA.) The new Virtual Clock
capability in SmartTime 7.3 enables you to specify a constraint for
a clock that is running outside the FPGA, and thus do timing analysis
on the design as it interacts with this "virtual" circuitry.
SmartTime Timing
Changes
- A3P timing is updated, now based on the silicon
characterization. This update includes all A3P devices except the
A3PE600. The impact on timing for existing designs is minimal.
- Enhanced Min Delay (EMD) support for ProASIC3 —
SmartTime now provides support for precise minimum delay/hold-time
analysis based on A3P characterized silicon timing data. This new
feature eliminates the need to over guard-band a design for minimum
delay, providing a more comprehensive, precise way to perform chip-to-chip
evaluation of external setup/hold and clock-to-out timing.
- UFROM Clock-to-Out timing has been extended for
A3P250 and A3P1000 devices. If your A3P250 or A3P1000 design includes
a UFROM, re-run SmartTime to obtain the correct timing information.
- FIFO Write Enable (WEN) and Read Enable (REN) setup time is
increased by a depth dependent delay to better align with the silicon
capability. (A3P250 and AFS600 Rev A/B)
- IBIS model for the APA1000 FG896 is updated to include
support for MIL temperature.
SmartPower
- Initialization with SmartTime Timing Constraints – links
SmartPower to SmartTime. For each clock in SmartPower, the equivalent
clock and its constraints are found in SmartTime. The power is then
calculated using the user's actual timing constraints. This approach
gives a more accurate view of the power consumption based on actual
expected operating frequencies, and enables the user to keep frequency
information between SmartTime and SmartPower in synch.
- Advanced Power Analysis for Fusion – Now includes
analysis for all Fusion-specific low-power modes
- adds Analog Block, Embedded Flash Memory, RC and Crystal (XTL)
Oscillators to "Type"
- adds VCC3.3A analog to "Rail"
- analyzes power contribution for the A/D converter Quad blocks
- Advanced Power Analysis for Memories – This
feature adds the capability to view power consumption for memory blocks
such as RAM, FIFO and embedded flash memory based on specifics of the
memories, such as number of active bits, aspect ratio of the memory
blocks, the number of memory blocks, etc.
- An Instance Properties Pop-Up box can be accessed
with a right click on any instance in the Analysis Tab. The pop-up
box provides detailed information about the selected instance.
- Improved Thermal Analysis and Static Power Calculation:
Static Power calculation is now based on Junction Temperature. Two
modes are available:
- Mode 1: Tjunction is stable as a function of Operating Condition
only. The Operating Condition can be changed in the preferences
window.
- Mode 2: The user changes Tambient and the Thermal-resistance
is used to compute T-junction. If the estimated T-junction exceeds
the Maximum of the range, a warning is issued

Algorithm (UMA) options (61264)
The Program File Generation User Interface for RTAX-S is enhanced to accommodate
a new programming algorithm (AFM) to be used for UMC production devices.
The "Fuse Export Options" UI Dialog Box now provides selections
for either OPA or UMA AFM generation. The specific device selections are:
- RTAX4000S: UMA support only
- RTAX250S, RTAX1000S, RTAX2000S: UMA and OPA support
- Default selection is for OPA AFM generation
New Macros
Pipelined FIFO has been added for Axcelerator devices. The details are

Online Help
61973 - Online Help on Linux and Solaris Operating
Systems does not include 7.3 updates. Online Help contains
Libero/Designer v7.2 SP1 Content. For Libero/Designer v7.3 help, please

Block Design Flow
59174/60119 - Generics
and Parameters are not supported in Block instantiation in the Top
level Design (All Devices)
60369 - Do not instantiate a Block component
more than once.
The Block flow in 7.3 is limited to one instantiation of the block. Libero
does not issue a warning if more than one block is instantiated into
the design, however Designer will fail when the netlist is compiled.
Instantiating multiple blocks in the block flow is a future enhancement.
Designer
60732 - Export
SDF TCL command failure (All Devices)
61444 - Spine
support is disabled on A3P030 and AGL030 devices
62374 - Syntax error in STAPL player when using
encrypted files (A3P/E, AFS)
An encrypted A3P/E, AFS, M7 STAPL file is not compatible with Actel's
STAPL player. A syntax error will occur when the file is executed through
the player. FlashPro and Sculptor software are not affected.
Designer Compile
61348 - Designer
compile error message does not reflect AGL030 RAM support correctly
62092 - A3P030 or AGL030 designs in the VQ100
package do not support all 6 CLKBUFs. A design that contains
6 CLKBUFs using this die and package will issue a compile error. Only
5 CLKBUFs can be instantiated at this time.
SmartGen
61893 - SmartGen does not differentiate core
selections for A3P030/AGL030. A3P030 and AGL030 devices do
not contain PLLs, RAMs, or FIFOs. (see specifications for these devices
at http://www.actel.com/products/igloo/ and http://www.actel.com/products/pa3/).
When designing with these devices, SmartGen includes PLLs, RAMs, and
FIFOs in the available cores list, and the devices can be selected
and configured for the design, but the design will fail later in the
flow. Do not select these cores when using these devices.
MultiView Navigator (MVN)
62087 - Incorrect count of I/O region resources
for A3P/E and IGLOO/e. The IO resource count (region properties)
is counting the unbounded IO as an available IO resource.
Workaround: There is no impact on user really
since the Design Rule Check (DRC) will not allow you to do any assignments
to the unbonded I/Os. This issue is only a resource display issue.
62086 - Properties dialog box shows incorrect
ADLIB name for the User Low Static ICC (ULSICC) core. (IGLOO/e) When
you right click and Select Properties on an instantiated ULSICC macro,
the name of the cell in the properties dialog in the MultiView Navigator
(MVN) appears as "ADLIB:UUSERB". It should appear as "ADLIB:ULSICC".
Workaround: The tooltip in the MVN shows the
correct cell name.
62462 - Show Routes option is not functional
in v7.3 (ProASIC/ProASICPLUS)
The "Show Routes" option in the MVN, which has been functional
in previous versions, is not functional in v7.3. The RatsNest display
however is functional. This issue will be fixed in an upcoming release
SmartTime
62341 - External setup/hold displayed in the
Summary have a wrong value (All Families)
The worst external recovery value for a clock domain is set instead of
the worst external setup value in the summary (in the GUI and the timing
report) when the clock domain has an external recovery and removal/recovery
checks are enabled.
Workaround: The correct external setup values
are displayed in the list of paths.
Disabling removal/recovery checks will fix the values in the summary.
62342 - The datasheet does not show the external
setup information for generated clock domains (All Families)
The SmartTime datasheet does not show the external setup information
for the registers which have the generated clock as their clock source.
The SmartTime datasheet should show external setup information with respect
to the external clock.
62344 - LVDS clocks are not shown under the
Explicit Clock (A3P/E)
Differential input signals have two inputs, which are joined by a buffer.
This causes the potential clock to be ignored. In the SmartTime Add Clock
interface, you can add the output of the differential buffer using the
GUI, but it will not provide timing data for that path. Only adding the
individual differential pins will provide timing data for the path.
62345 - SmartTime shows false violation for
a path that does not exist (APA)
For nets and cells removed by Designer compile, SmartTime uses a 0 delay.
In some cases, this can lead to false min delay violations.
Workaround: Check the differences between
the optimized and the original netlist in netlist viewer to check if
it is a false path.
62346 - The Bottleneck Report "cost_type
- path_count" option is not working in Tcl (All Families)
A Tcl script "cost_type - path_count" does not work correctly.
The report will generate correctly using "cost_type - path_cost".
The option works correctly in the SmartTime Graphical User Interface.
62347 - Minimum Pulse Width is 0 for IO cells
in A3P030. This will only affect the maximum frequency for
clock domains without register-to-register paths or with short register-to-register
paths.
