PlanAhead Design Assistant - Does the slack histogram show TRCE or PlanAhead Timing Analysis Results?


When I create a slack histogram after implementing my design, does it show the TRCE sign off numbers or PlanAhead's estimated Timing Analysis?

NOTE:This Answer Record is a part of the Xilinx PlanAhead Solution Center(Xilinx Answer 37100).The Xilinx PlanAhead Solution Center is available to address all questions related to the PlanAhead software.Whether you are starting a new design with PlanAhead software or troubleshooting a problem, use the PlanAhead Solution Center to guide you to the right information.


The slack histogram is created from PlanAhead's Timing Analysis numbers regardless of whether it is run before or after the design is implemented.

For more information on the difference between the results from PlanAhead Timing Analysis and TRCE results, see (Xilinx Answer 37461).
