#41 pipe mode?

[Samir Sabri]

Hello

I am very new to ngSpice, I tried to refer to the manual, but I did not find an example of using ngspice in pipe mode, can some one please show a simple example here for a minimal circuit?

In the pipe mode option (-p) ngspice reads from an input pipe. The input file sent via the pipe may contain any of the commands described in chapt. 17.5 of the manual. Ngspice executes the commands immediately and then exits. A simple example is given below. The program cat writes to the pipe, ngspice reads it.

The command file is:

*pipe-circuit.cir
source circuit.cir
tran 10u 2m
write pcir.raw all

The test circuit is

* Circuit.cir
V1 n0 0 SIN(0 10 1kHz)
C1 n1 n0 3.3nF
R1 0 n1 1k
.end

The command for starting ngspice is:

$ cat pipe-circuit.cir | ngspice -p

Thanks Holger, that’s exactly what I was looking for.
