PolarFire FPGA VICM Clarification for HSIODescription:This is a PolarFire Datasheet documentation change to the note for table 16 which relaxes the HSIO differential receiver maximum input common mode from a maximum VICM value of VDDI � 0.4 V to a new maximum VICM value of VDDI 0.24 V.Reason for ChangeThis change is to correct the PolarFire Datasheet table 16 notes that were too restrictive for HSIO differential receiver input common modes maximum ranges.
Maximum Read Frequency on Certain LSRAM Read Modes Has Been Reduced.DescriptionThe following LSRAM configurations have derated FMAX specifications.Reason for ChangeOn-going QA testing and verification exposed a timing criticality in a critical path within the LSRAM.Application ImpactUsers should upgrade to Libero 12.6 and re-run static timing using SmartTime if they are using one of the above LSRAM configurations and the design is running faster than the new limits listed in the table above.Method of Identifying Changed ProductBy part number.
Ongoing Software Quality Testing on Libero SoC Has Found a Static Timing Analysis (STA) Coverage Issue for Specific Scenarios for SmartFusion2, IGLOO2, RTG4, and PolarFire Product Families.Description:With Libero SoC v12.5, Libero SoC v12.5 SP1, and Libero SoC v11.9 SP6, netlist tie-off information is now correctly being passed to SmartTime for a complete static timing analysis.Reason for Change:Post-Layout timing database information for combinational cells inputs with constant tie-offs ("1" or "0") was incorrectly passed to SmartTime, preventing complete analysis of the path through the combinational cell.
Description:A change has been implemented to the PolarFire two-port large SRAM configurator and dual-port large SRAM configurator. The LSRAM configurator engine for the Write Byte Enable selection divides the entire width of the memory into equal fragments controlled by each Write Byte Enable bit.Reason for Change:The PolarFire LSRAM configurator engine in Libero SoC v12.4 and prior releases could generate unequal fragments for each Write Byte Enable selection bit. Typically, the total width of the memory would have been divided into fragments of 10 bits and the most significant fragment would be the remainder bits. For example, a two-port large SRAM memory with write width of 16 and the Write Byte Enable selection would be divided into 10-bit and 6-bit fragments.The change is applied to the following:-PolarFire two-port large SRAM configurator-PolarFire dual-port large SRAM configurator
DescriptionA change has been implemented to the PolarFire two-port large SRAM configurator, dual-port large SRAM configurator, and CoreFIFO. The LSRAM configurator engine correctly generates asymmetric width configurations and optimizes the area for high-speed and low-power selections.Reason for Change:The PolarFire LSRAM configurator engine in Libero SoC v12.4 could generate incorrect and sub-optimal configurations of asymmetric widths for certain multiples of 64 or 72. Asymmetric width configurations occur when the width of the two ports of LSRAM are not equal (for example, a FIFO, where the width of the write port is 36 and the width of the read port is 72).The change is applied to the following:-PolarFire two-port large SRAM configurator-PolarFire dual-port large SRAM configurator-CoreFIFO
