ngspice又一个电子CAD仿真软件代码.功能更全

2002-01-03 Paolo Nenzi <[e-mail]>

	* Added some code that adds new functionalities if 
	  ngspice is compiled for Windows (Holger Vogt patch)
	  I think that the new code interactively displays the
	  percent done of the analysis.

2001-01-23 Paolo Nenzi <[e-mail]>

	* noisean.c: patched the code with the new one
	in the bsim4.1.0 distribution. The new noisean.c
	put some code between #ifdef INT_NOISE. 

2000-01-21 Paolo Nenzi <[e-mail]>

	* cktsgen.c: corrected a bug that caused segfault on sensitivity
	analysis. 

2000-07-28  Arno W. Peters  <[e-mail]>

	* cktpzstr.c: Reversed a patch that went in between ng-spice-0.2
	and ng-spice-0.3 that eliminated the following warnings: 'suggest
	parentheses around && within ||'.  The parenthesis were not placed
	correctly, leading to incorrect behaviour of the pole-zero
	analysis.

2000-05-22  Paolo Nenzi <[e-mail]>

	* cktpzstr.c, cktsens.c: Applied Widlok patches.

2000-04-04  Paolo Nenzi <[e-mail]>

	* noisean.c: Merged the previous code with the new one included in
	             bsim4 distribution. This code originated from Weidong Lu 
		     (bsim group).

	* noisean.c:
          Bug: The ac noise analysis in Spice3f4 has a serious bug. In 
	  interactive mode it fails to reproduce frequency dependence known 
	  to exist.  In batch (Spice2) mode, it works only if a corresponding 
	  ac analysis has been run first.
          Fix: This bug is fixed by providing a call to CKTload() in 
	  noisean.c as shown  by the source code patch which is attached below.


1999-09-08  Emmanuel Rouat  <[e-mail]>

	* ckt.h: created (and included in Makefile.am) 

1999-09-07  Arno  <[e-mail]>

	* cktpzstr.c: reformatted and corrected(?) complex if condition.

1999-08-28  Emmanuel Rouat  <[e-mail]>

	* Removed all #includes of misc.h and util.h (now in spice.h)

1999-08-27  Paolo Nenzi <[e-mail]>

	* Removed GENERIC and #include "suffix.h" from all the files.
	GENERIC has been replaced by void. ANSIfied all functions with
	protoize.

1999-08-26  Paolo Nenzi <[e-mail]>

	* cktacct.c: added #include "spmatrix.h" to avoid implicit declaration
	warning at compile time.

	* dctran.c: ansified and substituted void with void.
	* tranasq.c: same as before.
	* traninit.c: same as before.
	* transetp.c: same as before.

	
1999-08-08  Emmanuel Rouat  <[e-mail]>

	* Removed all HAS_SHORTMACRO and HAS_FLATINCLUDES code in directory 

	* cktdest.c (and other files): changed HAS_SENSE2 in WANT_SENSE2  

1999-08-04  Paolo Nenzi  <[e-mail]>

	* changed dctrcurv.c: added code for temperature sweeps and 
	resistance sweeps. Now you can execute .dc temp <start> <stop> 
	<increment> to do a temp sweep, temp is the keyword for temp 
	sweeps (The code comes from  a patch supplied by Serban-Mihai 
	Popescu <[e-mail]>. To do a resitance sweep just 
	insert resistor name to the .cd line:.dc vin -5 5 1 rin 100 1000 10.
	Resistance and temperature sweeps can be nested.
