simvision analog variables and signals display issue

mxgong

Hi,

I am running ams simulation in the interactive mode.

However, the simulation has gone through, but I can only observe the digital signals. All analog signals (including inputs and outputs) and variables within the analog begin block are showing no value in the waveform window.

Here vin[8] is a net in the testbench schematic. triggers_out[x] are digital signals. Ceq is a real number inside the analog begin block.

When I stop the simulation and open result browser, the signals in schematics are saved there.

Thanks

Minxiang

    Minxiang,

    Which XCELIUM and SPECTRE sub-versions are you using? (these will be reported in the simulation log)
