Title: An error when simulating t&h circuitry
Post by ywguo on Jan 25^th, 2008, 2:11am

Hi Guys,

When I simulate the example, track and hold circuitry, in Ken's Simulating Switched=-Capacitor Filters with SpectreRF, the simulation is terminated with a fatal error shown below.

Quote:

======================================
`harmDisto': time = (50 us -> 52.5 us)
======================================
......9......8......7......6......5......4......3......2......1......0
Conv norm = 151e-03, max dV(SH.hold) = 5.2889 mV, took 10 ms.

Fatal error found by spectre during periodic steady state analysis, during
Quasi-Periodic Steady State Analysis `harmDisto'.
Arithmetic exception.
Warning from spectre during periodic steady state analysis, during Quasi-
Periodic Steady State Analysis `harmDisto'.
Failed to open save_restart file . Restore is ignored.
Failed to save the states into the file on analysis harmDisto

The whole simulation is logged in the attached file.

Any comments are aprreciated.

Hi,

I tried to attach the log file in this post several times. All failed, :( because I didn't notice that only a file with specified extension is allowed to be attached to the post.

I am sorry to attach the log file late.
