    Subject: [oc] has anyone got uCore to work?
    Top

    Dan and All,

    Has anyone else made progress with uCore under Icarus?
    I was also able to compile and run ucore_tb.v but I got the
    same results as Dan (not proper execution).

    I was unable to compile ucsys_tb.v, an internal
    Icarus error was generated.

    I will be spending some more time with this but I thought I would check
    to see if anyone had made some progress.

    Any tips would be great.

    Tim
