Hi, all :

I intent to read external functional patterns in VCDE format by TetraMax, but there are error messages as follow :

"Error: Program Error: unhandled pattern type=0 in VCDE flush routine "
Click to expand...

The VCDE external pattern is created by the vcs system task $dumpport :

Code: 
"$dumpports(top_module_name, "file_name",,2);

and the TetraMax command to read it is :

Code: 
"set patterns external file_name.vcde -vcd_clock auto -strobe rising CLK -strobe offset 70 ns"

Would you please advise me of how to fix it ~~~ !

Thanks very much ~~

Best Regards
