What hapened to STL?

Hello
In my old university we were using cadence with HSPICE and STL in
order ot perform post-layout simulation (back in 98). Now I got to a
new university but everybody is clueless about cadence software, and
the procedures I used to know do not work anymore. I have the
impression that STL (Simulation Test Language if I remember well) must
be gone for good, since I could not find any reference of it anywhere.
Is there any way I could enable STL somehow (I need to define
vectors for my simulation). If it is not possible, what are the
alternatives, and where should I look for particular information (the
cadence documentation database is huge so if you can provide a specific
book or link in the web, please do so). Spectre or spice, I do not
really care as long as input vectors can be defined; since I am doing
work with digital circuits, my stimuli is digital too.

Happy new year

Support for STL in the Analog Design Environment was dropped many years ago.

I'm pretty certain the code has gone completely... in fact from a quick bit of
searching, it was removed some time prior to IC443, and even then that was
just the last vestiges. Some of the docs didn't get tidied up for a couple of
releases after that.

There are some enhancement requests for spectre to support a digital vector
file stimulus. At the moment you could do that by transform it into a
piece-wise linear source set, perhaps (with a bit of perl, for example).

Ultrasim does support some digital vector formats (e.g. VCD) if you can use
Ultrasim instead.

Regards,

Andrew.
