How to run a regressive test and merge the ncsim.trn file of all test into a single file to view the waveform in simvision ?

sriganeshd

Hi all,

         I want to know how to run a regressive test in cadence and merge all ncsim .trn file of each test case into a single file to view all waveform in simvision. I am using Makefile to invoke the test case.

         eg:-

               test0:

                     irun -uvm -sv -access +rwc $(RTL) $(INTER) $(PKG) $(TOP) $(probe) +UVM_VERBOSITY=UVM_MEDIUM +UVM_TESTNAME=test0

             test1:

                   irun -uvm -sv -access +rwc $(RTL) $(INTER) $(PKG) $(TOP) $(probe) +UVM_VERBOSITY=UVM_MEDIUM +UVM_TESTNAME=test1

          I just to call test0 followed by test1 or parallel both test and view the waveform for both tests case.

        I new to this tool and help me with it

                     

  • I don't understand why you would want to do this; normally tests are easier to debug if you keep them short and simple, why would you want to combine them all into a single waveform file? What would it even mean to merge them?

    Hi StephenH

                 Thanks for your reply.  I just wanna run a regressive test.  I have done this in my old company with another tool.  I don't know how to do this in cadence.  I am doing the regressive test for coverage. when I call two tests continuously the coverage file in cov_work is getting overwritten.  I want to merge all coverage file for each test to make it a single file, i could get more coverage.

    waveform is not required,  just coverage.
