The HSPICE / BSD-spice bsim model differences have come up before here at Multigig. To that end a perl script was made to reprocess BSIM model files, it correctly adjusts L, W, PD etc. (I hope) and makes a BSD-spice model file, it can be found at: http://sourceforge.net/projects/rtwo/ ( it's called spicepp ) I was made be carefully reading the HSPICE manual and programming in all the relevant formula. I am not sure how usable it is, but the code for bsims is at the bottom of the perl script, I wrote that part (thus blame me for it's quality) Stefan On Mon, 2003-06-23 at 13:32, Martin, Mark wrote: > No, I was not sure and a recent message from Stefan, clearly > shows that I am wrong.
