dwarning 284d4308db Add optional switch for separate bottom and sidewall diode model - configuration is dependent from model parameter RSW 
Further sidewall knee current parameter IKP is implemented.

Brian Taylor 4f5c23ba44 Add a correction to the previous change of inppas4.c, which freed devname and left instance name pointers in DEVnameHash pointing at freed memory. This commit adds the devname string to the symbol tables which are eventually cleared by INPtabEnd. Also, if a capacitor in the spice netlist has the same name (unlikely, but possible) as a shunt capacitor, then no shunt is created, and a warning is issued. 2025-10-03 15:42:58 +02:00

Brian Taylor 57dd3342ef Enable CIDER with KLU for DC, OP, and TRAN analyses. Small signal AC analysis is not yet supported for CIDER complex valued device KLU matrices. The examples/cider testcases produce printed simulation result values which have slight differences between Sparse and KLU. Differences are probably expected and in a few cases are ~1-2%, sometimes a little more. This should be good enough for most CIDER analyses. Francesco did a good piece of work. Runtimes are significantly shorter with KLU. 2025-09-08 23:33:41 +02:00
