Problem
Cadence documentation appears to be totally inaccessible at ISU! When trying to load the Cadence documentation with the command cdsdoc the following error message appears:
/usr/local/cadence/ic/tools/jre/bin/java: error while loading shared libraries: libpthread.so.0: cannot open shared object file: No such file or directory
Solution
No word on a solution for this.
AMI (ON Semi) 0.5u tech library inconsistency - temperature coefficient
It has been observed that the BSIM3 parameter ute is assigned a value in the default tech library which does not match the test data available on the MOSIS website. The value in almost all of the test runs is -1.5 whereas the tech library value is -1.0. This parameter is the exponent that determines the temperature coefficient of the electron mobility; if you are working on temperature-critical designs or temperature-compensating a circuit, it is recommended that you copy the default tech library, ami06.scs from /usr/local/cadence/iclocal/ncsu_local/models/spectre to a local folder, make the modification, and carry out the new simulation with the new library. You can load it in your Analog Design Environemtn under Setup->Model Libraries.
