Details of Identified Issues
1. Details of Identified Issues
Nine issues have been identified and can affect the functional safety designs when using the IEC-61508 certified Libero SoC 11.8 SP4 and CoreGPIO.
1.1 Smart Time: Over-Optimistic Clock-to-Out Delay for LSRAM
Problem Description
There is an optimistic clock-to-out delay when using the SmartFusion 2/IGLOO 2 LSRAM under a specific configuration, which might give unreported silicon violations.
Condition of Occurrence
Write Feed-Through Mode is on (WMODE = 1) and the Write enable is low (WEN = 0). 1.2 I/O State during Programming is not Invalidating Generate Bitstream Problem Description
I/O State During Programming settings are not propagated to the programming file and “Generate Bitstream” state is not invalidated.
Condition of Occurrence
I/O State during programming is not set according to the settings that the customer set in the “I/O State During Programming”.
1.3 Optimistic Local Clock Network Delay when Local Clock RGB Area Coverage is too Wide
Problem Description
Designs using clocks, routed towards the global network through an RCLKINT macro, may require the cascading of multiple Row Global Buffers (RGBs) if the loads on that clock, cover a large area in the device. In this case, the clock skew between distant FFs might be larger than the span of what is expected in a local area. In extreme cases (large device, short data path, or distant FFs), a skew-induced timing violation can exist that is undetected by the tools.
Condition of Occurrence
The exposure to this issue is limited to SmartFusion 2 and IGLOO 2 designs with local clock nets, using only the largest devices such as, M2S150 and M2GL150 and their variants.
1.4 DAT Bitstream File is Incorrect when using Programming Recovery Problem Description
If the Libero design has Programming Recovery enabled in the Configure Programming options tool and uses Enable Custom Security Options in Configure Security tool, the DAT bitstream file generated will be incorrect and will not erase the security completely on the device when running the Erase action.
Condition of Occurrence
SmartFusion 2 and IGLOO 2 designs with Programming Recovery enabled in the Configure Programming options tool and uses Enable Custom Security Options in Configure Security tool.
1.5 Inconsistent SmartTime Behavior for DDR
Problem Description
Designs which applied multiple, duplicate, or overlapping constraints could face a scenario where SmartTime did not apply the last valid constraint entered, but instead applied a combination of the duplicate constraints.
Condition of Occurrence
Designs with multiple, duplicate, or overlapping constraints on DDR inputs applied to the same pin.

1.6 Clock Generation Value is 0 ns for Muxed Clocks
Problem Description
Timing model of CCC does not account for CCC CLK1 input resulting in clock generation value of 0 ns for muxed clocks.
Condition of Occurrence
SmartFusion 2 and IGLOO 2 designs where CCC CLK1 input is used in generated clock constraints.
1.7 CCC SmartTime vs BA Simulation: Delay from Input PAD to CCC GL has a Mismatch
Problem Description
For designs containing CCC with internal feedback, incorrect port name is written in the SDF file due to pin swapping. This results in a delay mismatch between SmartTime vs back-annotated simulation.
Condition of Occurrence
SmartFusion 2 and IGLOO 2 designs containing CCC with internal feedback.
1.8 Mismatch between SmartTime and BA Simulation on Outpad Delay Problem Description
SmartTime skips IOTRI_OB_EB and IOOUTFF_BYPASS instances in timing analysis yet back-annotated netlist still contains these two instances while back-annotated sdf file does not have them. This will cause back-annotated simulation to use default delays on these two instances resulting in a delay discrepancy between back-annotated simulation and SmartTime.
Condition of Occurrence
SmartFusion 2 and IGLOO 2 designs containing Output pads.
1.9 Simulation Issue Found with CoreGPIO v3.1 when VHDL HDL is Used Problem Description
The APB slave address (PADDR) of CoreGPIO is not qualified with the PSEL signal. Due to this issue, any APB slave address outside the permissible range of CoreGPIO results in a simulation error. The issue in the IP does not have an impact in hardware validation.
Condition of Occurrence
The issue is observed only when HDL generated language option is selected as VHDL. The issue is observed if the APB slave address falls outside the permissible range of CoreGPIO. The permissible range is based on the CoreGPIO configuration.
