Hi,

I'm implementing table based charge source (two dimensional table).

I am using SDD component and a weighting function of one (i.e. I(p,1) where p is the port number). I have no problems when running HB, DC or Sparam simulation.

The problem comes when adding higher order time derivatives ( i.e. H[2] = (j*2*pi*freq)**2 ).

It doesn't converge in HB (although it converges in both DC and Sparam).

The same problem happens when I used verilog-A component instead of SDD.

Thanks in advance
