Reporting path delays from quartus flow into timequest report

Create a .tcl file(I always call it TQ_analysis.tcl) and put in a line:

report_timing -setup -npaths 20 -detail path_only -from [get_ports rx] -panel_name "s: rx -> *" -file "./TQ/rx_to_core.txt"

Manually run TimeQuest and source this file from the Script pull-down to make sure it works. Change the options as appropriate and look at the output file in the TQ directory. If it's what you want, then in Quartus go to Assignments -> Settings -> TimeQuest and add the file. It will run automatically for the slow cold timing model.

One other trick I sometimes do is add the following:

set seed [get_global_assignment -name SEED]

This just gets the seed setting, and I put it into the output file name:

-file "./TQ/rx_to_core_seed$seed\.txt"

You can then run a seed sweep and this path will be reported for each one. (I'm doing this on a design right now, which is why I mention it)
