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.
Customer Notification CN20003 PolarFire, SmartFusion2, & IGLOO2 Customer Notifications for Libero SoC v12.4 The document describes various changes to Libero SoC 12.4 Summarized here: � PolarFire FPGA System Controller Suspend Mode � Net list generated for W32xR2 and W32xR1 LSRAM asymmetric Two-port RAMs � "Configure I/O states during JTAG programming" tool � PolarFire FPGA PCIE Register Update Notification � Certain unused IOs were not tristated when programmed � Minor Update to PolarFire LSRAM CLK-to-OUT delays
Libero 12.2 Timing and P&R ChangesDescription of Change:Minor changes have been made to the timing parameters of sequential elements and select routing resources, including a tightening of the clock skew.These changes result in a minor impact on timing margins of existing designs.Reason for ChangeOur ongoing QA process highlighted the need to reclaim built-in timing margins to bring the timing model to the required quality levels.
Deprecated WD_TIMEOUT Port to the FabricDescription of ChangeExposing the WD_TIMEOUT port to the fabric in the MSS Configurator is deprecated starting in Libero 11.9 SP5 and Libero SoC 12.2.Reason for ChangeThe WD_TIMEOUT signal does not behave as expected when the watchdog timer timeout behavior is configured to generate an interrupt.
Subject: Libero SoC Timing Change and IO Glitch NotificationCAN 19010.1 Clock Source Latency CalculationDescription of the IssueDue to an error introduced in Libero SoC v11.7-SP1, when a clock source latency constraint is applied to a generated clock, an additional delay (= late – early) is incorrectly added to the net driven by the clock source and impacting the required time calculation. As a result, the clock source latency constraint is ignored on the generated clock. Up until Libero SoC v12.0, this constraint has been recommended as a way to capture clock jitter information and pass it on to be used by the static timing analysis tool, SmartTime, during its Max Delay Analysis.Reason for NotificationLibero SoC v11.9 SP2 and beyond restores the correct value for the data required time calculation. This correction is alsoaddressed in Libero SoC v12.0. The respective software release notes include a reference to this change. In addition, startingwith Libero SoC v12.0, jitter can also be modeled using simple clock uncertainty constraints.Action RequiredRe-run static timing analysis with SmartTime using Libero SoC v11.9 SP2 or later, if you are setting a clock source latencyconstraint on a generated clock and the margin you have is less than the constraint window (for example, jitter window).CAN 19010.2 IO Glitches During Auto-UpdateDescription of ChangeAuto-update is a method to automatically update the FPGA image on a power-up. If enabled, the system controller will check the design version of a bitstream in an external SPI flash and compare it to the programmed version. If the external bitstream is newer than the programed bitstream, then the system controller will use the new bitstream to program the device.If autoupdate is enabled, an auto-update action will occur. Under these conditions during device power-up or the de-assertion ofDEVRST_N, an IO glitch will occur on banks 0, 1, and 2 of the the M2S005/010/025 or M2GL005/010/025 devices. If autoupdate is not enabled, the glitch does not occur. The amplitude of the glitch correlates to the VDDI bank voltage level. Reason for NotificationIO glitches on banks 0, 1, and 2 of the the M2S005/010/025 or M2GL005/010/025 devices during auto-update programming mode.WorkaroundUtilize In-Application Programming (IAP) in place of auto-update.Move sensitive outputs to a non-glitch bank.
Addendum to PCN1309 and PCN1309A - Synopsys Synplify Pro Software Bug Regarding Safe State Machine RecoveryDescriptionMicrosemi and Synopsys have recently become aware of a scenario that can result in a state machine design not being implemented with logic circuits which force the state machine into a reset state if an illegal state is detected.Description of the ProblemWhen a design is synthesized with the one-hot state machine encoding style and includes state machines with only two states, Synplify Pro may not recognize them as state machines. If the state machine is marked for "safe" implementation, and this bug affects the design, then the inferred extra logic that forces a reset during an illegal state condition will not be added. This problem can occur only when all of the following conditions are true.The design is synthesized with the "safe" encoding style for the state machine (the user has specified syn_encoding=�safe�).The state machine is instructed to use "onehot" encoding through the Implementation Options > VHDL setting.The state machine has only two states.The state machine does not have a syn_state_machine="true" attribute.
