[Ngspice-users] ngspice .lib

[John B. <jb...@au...>]

Hello.

I am getting the following error, after including the library file (via 
a ".include"):

    Error on line 7 : .lib total
          unimplemented control card - error
    Error on line 10 : mdut0 3 2 9 9 pch_mac w=1.0000u l=0.0400u
         Unable to find definition of model pch_mac - default assumed
    Error on line 11 : mdut1 3 2 0 0 nch_mac w=0.5000u l=0.0400u
         Unable to find definition of model nch_mac - default assumed

I should be able to use .Lib 'filepath' lib_name (according to 
Meta-Software's HSPICE manual, dated 1996), but that does not work. This 
has been a pretty standard Spice for a long time, so I am curious as to 
how a ".lib" control card could go unimplemented.

I am trying to use open-source programs, particularly from gEDA, but 
they just do not work in an IC design arena. I do not understand why 
"Verilog AMS" function is more important to ngspice (tclspice), and 
iverilog, rather than having a functional open-source alternative to 
$10k, if not $100k, spice and verilog/synthesis tools. [Not to mention 
the lack of static timing, LVS/DRC, layout (is Magic dead?), and other 
useful tools]. I understand time and energy restrictions, and that 
contributions would help. But: give [small] design companies a real 
alternative to the huge price tags from Synopsis, Cadence, Mentor (and 
others), and there would be money to put to the place(s) from where the 
tools came. (I know that this is an ngspice  arena, but it is all from 
gEDA). IM(H)O, any corporation that uses these tools _successfully_, 
rather than HAVING to spend tens-to-hundreds of thousands of dollars, 
would "do the right thing" and provide funding in the thousand(s) range, 
at the very least.

Thanks for reading, and any movement in "my" direction.
