IUS583 does not support clocking blocks withing modports.(Section 20.4.5 of the LRM)Which version of IUS support it?
Thanks for the question. We've had support for clocking blocks in modports since our 6.1 release in April of this year. Our 6.2 release just posted to Sourcelink, so you might want to upgrade to that release. It offers a lot more language support, class-based debug, and it is the release our early adopters are using to run OVM.=Adam Sherilog
