I think it is better if you know some scripting language...like perl .. tcl is not needed. Some time
you might need to manupulate few things in
your spice here and there so it's better to
automate it ..
automatation will often cause wrong operation. If it's little change, do it by hand. if it's a very large task, tend to experienced script writer will be better.
script can help you improve the efficiencym, but it will also cause the problem such as the wrong operation and more time to debug the script if it cause wrong problem.
Perl is a powerful tool to help you quickly summarize simulation measure result from hundreds of files covering all corners(vcc, temperature, process and etc), and we love those scripts, they are very easy and useful.
Re: Does analog(or mixed mode) ic designer need script langu
If your company has good CAD team, you don't have to do anything on script. But if not (most time, it does happen), ability using perl, SKILL(Cadence), Amply(Mentor), or maybe awk could give you more power to ease your design work.
Re: Does analog(or mixed mode) ic designer need script langu
Everything has advantages and disadvantages..
Scripting enables you to do things very quickly but you might end up debugging your script too...
But I believe: "If you are doing something twice, script it"...
perl, awk etc aid you in doing many things in a very simpler way..
