** Fatal: Internal error on use of uvm_do_on macro With MTI 10.1c version

Recommended Posts


I face below fatal error while using uvm_do_on macro in Modelsim 10.1c version.

** Fatal: Internal error: ../../../src/solver/slvACTContext.c (1084)

My sequence is as below:

class sample_seq extends uvm_sequence;



sample_abc_seq abc_seq;

function new(string name ="sample_seq");


endfunction : new

task body();

if( p_sequencer.abc_sequencer!=null)

`uvm_do_on(abc_seq , p_sequencer.abc_sequencer);



Can anyone help me to figure out the issue in this approach??

First, you should never get an internal error from any tool. Contact Mentor directly with more details about the platform/OS you are using and the command line used to invoke the tool. It also help to show as much as possible in the output before the error occurred.

Second, You can not use `uvm_do_ with Modelsim because it calls abc_seq.randomize(). You need Questa to do that.
