[Ngspice-users] What Linux for NGspice

[Juan S. <jua...@gm...>]

What version of Mandrake do you recommend to install ngspice. I have tried

Holger,

    Your suggestion works perfectly.  How did you come up with that?  
Was it magic?

>>Reply-To: ngs...@li...
>>
>>Has anybody seen this behavior before.
>>
>>I made my schematic resistors "look like" the way I wanted my layout 
>>designer to lay them out i.e. if there were 150- 2k segments then I made 
>>my schematic (and netlist) show 150 series connected resistors.  As the 
>>circuit got bigger I started to get more errors like "segmentation fault 
>>- check nodes blah blah", the transient analysis would not run, all the 
>>node voltages were zero.  The "blah blah node" was some node on the 
>>series connected resistor that, upon inspection, did not really have any 
>>syntactical or topological problem.  When I "smashed" the series 
>>resistors into a much smaller number of resistors the error messages 
>>went away and the simulation ran and gave me an answer that I expected.
>>
>>Is this just a general matrix problem with ngspice?  As the matrix gets 
>>bigger and bigger are more problems like this bound to happen?  Does 
>>anybody have any comment on this?
