Black Blox Creation

jesolano

I have a doubt about CREATE BLACK BOX:

I have a testbench where I am trying to simulate two separate RTL designs that share some module names within their designs. I have tried compiling and elaborating them separately and then referencing their libraries but I still get error.

On Incisive Enterprise Simulator -> irun -> Elaboration Command Line Options -> Elaboration Command Line Options -> 1.2 ncelab Command options -> 1.2.20 -BBOX_Create directory have a example of how to create a Black Box, however I did all the steps of example 4 and did not work!!!!


print the following error:

irun -primname ip1 -bbox_link ./tmp/box1 -primname ip2 -bbox_link ./tmp/box2 soc.v
irun: 15.10-s002: (c) Copyright 1995-2015 Cadence Design Systems, Inc.
irun: *E,DYNWKP: unable to locate the primary irun invocation from -PRIMNAME ip1.
irun: *E,DYNWKP: unable to locate the primary irun invocation from -PRIMNAME ip2.
irun: *E,DYNMPN: unable to locate primary snapshot from -PRIMNAME ip1.

Can you help me, about this?

  • You do not want the black-box function, this i for excluding parts of the design completely and you can't simulate if you do that.
    You need the MSIE flow; you'll need to snapshots, one with your DUT_1 and the first version of the package, and the second with your DUT_2 and the 2nd version of the package. There is a really good rapid adoption kit (RAK) for MSIE on this page: support.cadence.com/.../cos;src=wp;q=ProductInformation/Functional_Verification/Incisive_RAKs/Incisive_RAK.htm
    look under the "Performance" section for the "Incremental Elaboration" RAK.
