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.

09f070f582
Error handling improvements in cfunc.mod. Ensure that d_process.h wiil always respond to version and interface checks sent from sendheader. This is needed so that the pipe reads in sendheader do not cause Windows to hang when the interface version and in/out counts do not match. This hang was the cause of errors not being reported and the Windows gui hanging. Startup and header checks are now detected in cm_d_process, and the simulator will run but with runtime errors since a d_process model cannot be completely instantiated after initial errors. It would be good to find a means of gracefully halting the simulation run.
2023-10-28 11:00:33 +02:00
4530cde8e2
Use Xspice cm_message_send to report errors rathen than printing to stderr and calling exit. When a d_process model has errors found in start(), sendheader(), and dprocess_exchangedata() these are reported, but if the model is run a SIGINT is raised. There must be a better way of stopping the simulator.
