Re: [oc] Simulation Tools

Hello Rudolf and John,


Thanks a lot for ur replies....

Can u tell me what is IMHO in relation to the simulation tools? 

I am really getting feature wise difference in the simulation tools u 
mentioned in the reply. Can I get the cost wise difference? Like 
supppose one wants to go for an economic solution for the simulation 
tool, ofcourse not at the cost of performance, then for which tool it 
should go for?

Thanks in advance,

Regards,

VLSI CHAMP....
