fsdb file not refreshed during simulation

Hi,

I have ADE output format set to fsdb, and planned to read waveform from spectre transient simulation from a waveform viewing tool.

The issue is that I waveform doesn't show while simulation is on-going, evidenced by the fact that fsdb file size doesn't grow, spectre.out file does grow.  don't know whether there's be an update from spectre.out to fsdb when the simulation finishes. (will update later).  but expect fsdb file refreshed  during the simulation to see wavefrom instantaneously.

thanks,

Kevin
