[Ngspice-devel] WinPC output from ngspice

[Richard F S. <ric...@bt...>]

Greetings.

I hope this first post is not tiresome and obvious to experienced 
ngspice users and developers.  I am a specialist hardware engineer 
who can get by in C, ABEL and Assembler; I like nice, simple, old-
fashioned and obvious languages, such as Spice.
 
I've been using Spice 2G and 3F to design my analogue circuits for 
almost two decades on Solaris and Amiga.  But, since retiring and 
no longer having my lovely Sparcs to play with, and the '060 Amiga 
dying recently from a lightning strike via the modem, I've had to 
resort to using a WinPC for this latest project.  So yesterday I 
was delighted to find ngspice under active development.

My problem is simple.  I cannot get any useful output from ngspice, 
even when trying previous proven scripts for 2G6 and 3F5.  I used 
ngspice19-080425.zip expanded into C:\Spice under Win2KPro.

The program will see the source files and happily run, but if I use 
any of my simple netlists (2G6 format) say testfile.cir there is no 
_useful_ PLOT or PRINT visible for any dynamic tests, and trying to 
'save testfile.out' is accepted but there is no file saved anywhere 
in the PC. 

All I really need is 2G6 functionality.  Attached are a pair of inp 
and out files that were first run on the Amiga and had the same 
successful results on Solaris Sparc.  But, when tried with ngspice, 
there is no useful output visible with any of the commands I have 
been able to try, even though ngspice reports the required number 
of 'data rows' being produced.

The cs_mixtv4.out output file is exactly the sort of thing I want, 
all the relevant data is there at a glance, produced from the Spice 
command options embedded in the source file, but how to achieve it 
with ngspice?

Sorry to be so long winded.

Many thanks in advance for any help.
