Hi, John.
Anonymous, please. I've been using ModelSim (PE, V5.3a), and discovered one
interesting "feature". If you have a waveform display up on the screen, and
want to save the format, it writes a Tcl script for you to execute later.
So far so good.
However, if your display includes large virtual signals (eg busses that you
have built on the display by combining individual signals), the Tcl script
is not executable when reloaded. It writes the bus description all on one
line, with no regard to the buffer length (I've seen lines almost 5000
characters long)! These, naturally, break the Tcl interpreter when read
back in.
I do feel it's rather poor for a tool to write a script that it itself
cannot read.
