(Mar 2005)
Thank you for your interest in Actel's Libero Integrated Design Environment
(IDE) v6.1 SP1. These release notes outline various updates for the v6.1
SP1 software.
ProASIC3
Support 
- Program (STAPL) file generation is enabled for A3PE600 ProASIC3E
- Requires FlashPro3 programmer and FlashPro v3.3 software
- Improved ACTgen PLL generator interface provides more accurate delay
numbers based on ProASIC3 capability
- New packages for ProASIC3

Other
device support additions or changes:
- Programming yield improvement for AX and RTAXS. This service pack
includes enhancements that may increase the programming yield for AX
and RTAXS devices.
- For RTAXS designs created prior to v6.1 SP1, the software will
automatically detect if the design will benefit from the v6.1 SP1
enhancements when the .adb file is opened. If yes, the previous routing
will be invalidated and the user will be prompted to re-route the
design using v6.1 SP1
- For AX designs created prior to v6.1 SP1, the routing will not
be automatically invalidated, however Actel recommends that the design
be re-routed so it can benefit from potential yield enhancements
- RT54SXS-S and RTSX-SU AFM updates to improve programming yield
- AFMs generated with v6.1 SP1 require Silicon Sculptor v3.87 (DOS)/v4.50.0
(Windows) be used for programming
- RTAX-S and AX
- Prior to Libero IDE and Designer v6.1 Service Pack 1, the Axcelerator
and RTAX-S simulation libraries did not accurately reflect an EMPTY
flag behavior. The libraries did not model an EMPTY flag temporary
low period after the release of CLR during the high RCLK pulse. These
simulation libraries have been corrected in Libero IDE and Designer
v6.1 SP1 to reflect the true silicon behavior of the EMPTY flag. An
apps note covering this issue is available.
- Added MIL temp range for A54SX72A FG256 and FG484 for STD and -1
speed grades
- Removed -3 speed grade for all Axcelerator (AX) devices
- The user will be informed if an existing .adb uses -3 and proceed
to automatically convert the design to -2
- Removed -3 speed grade for A54SX08A device
- The user will be informed if an existing .adb uses -3 and proceed
to automatically convert the design to -2
- Added RTAX2000S in CG1152 package

Requirements
for ProASIC and ProASICPLUS Users
If customers have not already done so, all ProASIC and ProASICPLUS designs
must be upgraded to Libero/Designer version 6.1 which was released January
2005. Downloads of this software are available at the
Libero IDE v6.1 Release Notes
or Designer v6.1 Release Notes.
Important place-and-route software changes have been made that must be
factored into your design to ensure proper handling of all conditions.
Windows NT Support
Libero and Designer will no longer be available or supported on Windows
NT after 2005.
GCF Timing
Support
GCF Timing Constraint support for ProASICPlus (APA) family is being
obsoleted. Libero and Designer v6.1 SP1 will be the last version supporting
GCF to SDC conversion for the following GCF timing constraints. Subsequent
releases of Libero and Designer will not recognize these constraints.
For any APA design-in-process that is expected to be completed on a future
software release, customers should remove these GCF timing constraints
from their GCF files and substitute them with an equivalent SDC constraint.
SDC files can be imported into Designer or generated by the Timer user
interface (pre-layout).
The GCF constraints to be obsolete after v6.1 SP1 are shown below, along
with the corresponding SDC.
| GCF Constraint |

| create_clock -period <period_value> portname |
create_clock -period period_value portname |
| create_clock -period <period_value> netname |

set_false_path -through through_list |
| set_input_to_register_delay <delay> [-from inp_port] |

| set_multicycle_path <num_cycles> -from reg_port [-through_any_port]
[-to_port] |
set_multicycle_path path_multiplier [-from from_list][-to to_list] |
| set_register_to_output_delay <delay> -to out_port |
set_max_delay delay_value [-from from_list][-to to_list] |
| set_max_delay -from first_pin_in_the_list -to last_pin_in_the_list |
set_max_delay delay_value [-from from_list][-to to_list] |
Libero IDE v6.1 SP1 requires a current Libero IDE v6.0 license.
