[SOLVED] Modelsim - Error generated by Wave window

[rakeshk.r]

Hi,
I am using HDL designer tool. Whenever I start to compile for the first time, the modelsim tool transcript shows an error (as shown below) first and then finishes the compilation. However this error doesn't affect the simulations. But I am curious to know why would this error be shown every time modelsim is invoked for the first time. Any idea what the error is about and any solution to fix it ? Thank you.

This is a problem with HDL Designer that was fixed in 2012.x. Apparently if a Wave Window is left undocked when ModelSim is closed this error will occur the next time ModelSim is invoked from HDL Designer.

There are three possible ways to work around this:

1. Dock the ModelSim Wave Window before closing ModelSim
   
2. Disable communication with HDS by means of the dedicated checkbox (Un-check Enable Communication with HDS) in the ModelSim Invoke Settings dialog window. This will also disable all interactive features like FSM animation, signal probing, simulation control, etc.
   
3. Update your software.
