Subject: Addition of Microchip-Thailand as a New Test Location for Microsemi FPGA Business Unit Products Group (Addendum)Description of Change: This notice is to inform you that Microchip Thailand has been added for product test and shipping processes for various products in all applicable product offerings. (See Appendix A for the list of affected part numbers.) The following are the various processes that can be performed at the additional location:a.) Electrical test (final test, QA electrical, and temperature testing)b.) Programmingc.) End of Line activities (EOL) such as baking, dry packing, coplanarity, pack/seal, and demark/add a markd.) Shipping and inventory managementReason for Change: The purpose of this PCN is to streamline manufacturing operations using Microchip's internal facilities.Application Impact: There is no change to form, fit, function, quality, or reliability of the product shipped from the new location.Products Affected by Change: See Appendix A for the complete list of devices.Product Shipment Schedule: Products from the new location are planned to ship no sooner than April 2019, unless the customer can provide a waiver for products to be shipped before April 2019. Post April 2019, customers may see shipments from all approved locations.Qualification Data: Documented information pertaining to this change is available upon request by CYQ2 2019.Samples Availability: Please contact your local Microsemi/Microchip representative to place sample orders as required.

Following are the various processes that can be performed at this location:a.) Electrical test (Final test, QA Electrical, Temperature testing)b.) Programmingc.) End of Line activities (EOL) i.e. banking, dry packing, coplanarity, pack/seal, denmark/add a markd.) Shipping and Inventory Managment
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.
