Copy value of a signal at a particular time: In simvision, there is no direct way of copying the signal data at a particular marker time, If you want to copy the signal value, do this: Open console form Window->Tools->Console Type in this command: "waveform values [waveform cur]". This will display the signal value on console, then you can copy the signal value from here. To get all signal values visible on the simvision window, use this command: "waveform values"
