09.02.2010 version 3.1 of visualspice loadflow dll's


16. 03. 2007 preliminary models derived from ( psat library ) for doing time domain transient phasor simulations ( synchronous generator , turbine governor , avg ) , examples follows ,  ( for pure transient time domain models see spicelab : www.softwaredidaktik.de/spicelab/  )


14. 03. 2007 ps2sp.pl V4.14 of ps2sp.pl and preprocessor_GUI.pl  , preliminary models for doing symmetric three phase short circuit calcultations  


16. 11. 2006 ps2sp.pl V4.11 with some enhancements in the subcircuitexpansion , libexpansion , parameter and functionexpansion - code


10. 11. 2006 ps2sp.pl V4.00 with some bugfixes in the parameter evaluation code,  NEW : functions as parameter to subcircuits allowed , NEW:  parametrized nested subcircuits of any level 


06. 10. 2006 some bugfixes and new savebias/loadbias feature in ps2sp.pl ( V3.06 )


17. 09. 2006 small changes in ps2sp.pl ( function tabel2bh )


15. 09. 2006 small changes in preprocessor_GUI.pl and ltspice_2_spice3.pl  


14. 09. 2006  changed function NEQ to NE in examples test_pfunctions.cir , test_functions.cir and corrected a bug in ps2sp.pl function expand_parameters()

11. 09. 2006 ps2sp.pl V3.04 ( correced small bugs in previous versions ), NEW: small manual for the preprocessor GUI , corrected a problem with the perl optimizer if the initfilepath contains blancs


07. 09. 2006 new version of spice preprocessor/postprocessor ps2sp.pl  V3.02


03. 09. 2006 new version of spice preprocessor/postprocessor ps2sp.pl V3.01  


13. 07. 2006 corrected small bug in ngspice-nutmeg bassed optimizer ( cpt_sum -> let sum=0 should be after the first while loop )


30. 06. 2006 some small bugs corrected in ps2sp.pl V3.0 . Now many testfiles added ( testsuite_ps2spV30)


23. 06. 2006 stable version of perl based spice preprocessor V3.0 ( now named again ps2sp.pl / ps2sp.exe ) . The older version is renamed ps2sp_old.pl . For new features see also ps2sp.readme

17. 06. 2006 NEW preliminary version of perl based preprocessor V3.0 ( ps2sp_new.exe/ps2sp_new.pl ) FEATURES: efgh-polysources , c/l poly lines , c/l expression lines ( q=expr and flux=expr ) , support for pspice V/Iswitch model , support for tc1,tc2 statements in R-Lines , more functions ( idt , ddt , stp , exp) and operators ( not~ , xor^ ) , support for .dc [OCT,DEC,LOG,LIST] param a 0 10 1 [OCT,DEC,LOG,LIST] param b 0 1 0.1  


16. 02. 2006 NEW nutmeg based optimizer for ngspice , new examples and description for VisualSpice , small changes in perlbased optimizer ( focus grabbing problem solved -> starting background process with "start"  ) , New perl based preprocessor GUI for pspice to spice3 converter


26. 12. 2005  in ps2sp.pl line 2635 changed from "foreach (@line)" to  "foreach (@_=@line)". Three month ago I unfortunately deleted "@_=" from the expression above. Without "@_" the .param .func and .pfunc statements in @line are deleted and therefore no local parameter or funclines for subcircuits worked any more !!!!  SORRY !!!


24. 12. 2005 added a NEW perl/TK GUI for preprocessor  ( ps2sp,  mm2cm  and rawfileconverter )


22. 11. 2005  a new codemodel for doing kalman filtering for spiceopus and many new codemodels ( also for loadflow ) for visualspice ( will be added at the homepage in Dec. 2005 )   The loadflow - documentation mathem_models_eng.doc completely revisted , all doc's now as zip files


20. 08. 2005  newer actual versions for prepro.zip (V2.2) and optimizer.zip ,  NEW Perl/TK GUI  for optimizer.pl , some new spiceopus codemodels like floor,ceil,integer,rand,timedelay (additional.cm) . Now the downloadpage is translated to english language 


03. 02. 2005  new examples and codemodels for spiceopus ( now all lfl-codemodels with additional measurementnodes ) to be compatible with the ltspice macromodels with the same name . The converter mm2cm.pl ( macromodel to codemodel converter ) translates the ltspice netlist to a netlist for spiceopus. The codmodel can now be simulated and even optimized (only spiceopus V203) in spiceopus and the results visualized again in the ltspice schematic   


20. 01. 2005  small changes in prepro.zip
