Question about SPARCT1 simulation with VERA or NTB

Hi every one:

There is a option in sims simulation: vcs_use_vera, what is it used for?

If I want to run simulation with vcs ,vera, shall I add this option? Is there some difference ?

Additinally, I want to run it with "ntb",the command is follow:

sims -sys=core1 -vcs_build -vcs_run -nouse_oolm vcs_use_ntb bypass_win.s

But there is errormessage:

gmake: *** No rule to make target `ntb_all` .stop

sims: Caught a SIGDIE: failed making vera testbench in ....

What is the reason for that? who can help me? Thanks

Hi,

Vera drivers and checkers are compiled by default in the model build so you do not need to specify vcs_use_vera option. To disable vera, you can specify -novera_build and -novera_run options.

Thanks for answering the first question of mine!Concerned with the second question, does opensparcT1.1.4 support NTB simulation? why I can not find any information about NTB in the sims script(sims,1.262)?

Hi,Sims has some basic support for NTB but current testbench included in the OpenSPARC T1 is vera based. Check "cvs -h" to see what options are supported.If you build NTB on your own then you should be able to use sims options supported in the script.Hope that helps.
