8 years ago --- Quote Start --- I will initialise d_reg to known value to keep modelsim happy --- Quote End --- Hi, Original code (before I stripped it down to bare minimum) had a sync reset for d_reg and still exhibited the same behavior. Added initial power on state ("= '0;") and it still did the same thing. In all three cases (reset, power on state, and the above code) the simulator shows the register output settling to '0' within a few ns of the simulation. I forgot to mention that the RTL simulation works as expected. Even if I totally stuffed up timing closure I'd still expect the clock to the driven... Any other ideas? -- Paul
