Sorry for the ambiguos statement; I should put this way:
In ADE if I want to have a user defined simulator (say custRunSim) which
can be seen in the pop down menu of simulators while cllick on
Setup->simulator/Directory/host..., how should I start or where should I look for reference.
How this customization can also callback a user defined analysis? Say, when user will choose the
custRunSim simulator it will also change the analysis option (like when we change the
simulator from spectre to aps lots of analysis option vanishes
