Soft Error Mitigation Controller v1.2 - After meeting timing, PAR reports hold violation upon running another routing phase

描述

Known Issue: v1.2, v1.1

ISE 12.4 and 12.3 PAR achieves a timing score of 0 and a subsequent routing phase introduces a small hold violation. The PAR report looks similar to the following:

Starting Router
Phase 1 : 142396 unrouted; REAL time: 2 mins 56 secs
Phase 2 : 99399 unrouted; REAL time: 3 mins 51 secs
Phase 3 : 9841 unrouted; REAL time: 5 mins 54 secs
Phase 4 : 9841 unrouted; (Setup:0, Hold:3967472, Component Switching Limit:0) REAL time: 6 mins 41 secs
Phase 5 : 0 unrouted; (Setup:0, Hold:3901462, Component Switching Limit:0) REAL time: 7 mins 38 secs
Phase 6 : 0 unrouted; (Setup:0, Hold:3901462, Component Switching Limit:0) REAL time: 7 mins 38 secs
Phase 7 : 0 unrouted; (Setup:0, Hold:3901462, Component Switching Limit:0) REAL time: 7 mins 38 secs
Phase 8 : 0 unrouted; (Setup:0, Hold:3901462, Component Switching Limit:0) REAL time: 7 mins 38 secs
Phase 9 : 0 unrouted; (Setup:0, Hold:0, Component Switching Limit:0) REAL time: 8 mins 29 secs
Phase 10 : 0 unrouted; (Setup:0, Hold:3, Component Switching Limit:0) REAL time: 8 mins 38 secs
WARNING:Route:452 - Not all timing constraints have been achieved. Please consult the `Post-Place & Route Static Timing Report' to determine the actual timing results.

解决方案

This small hold violation does not cause any problems and only occurs on the XC6VLX760 device.

This issue is scheduled to be fixedin ISE software 13.1.
