fsdb file not refreshed during simulation

Karev11

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

    update to this observation:

    Before simulation finishes, after  a longer time, noticed tran.tran.fsdb increased.  does that mean fsdb file increase/refresh every N Mbit?  if so, can N be reduced through some setting?

    This is a known issue, with some limitations caused by the fact that this is not a Cadence format (the APIs to write it are provided by a third party). Please contact customer support - there's an existing CCR 1917977, so please request a duplicate be filed against that. I don't believe there's any control currently which alters the flushing rate.

    Regards,

    Andrew.
