Hello Nitin, first of all I have to complete the vendor 'jump into the game' round and mention that there are of course as well Post-Layout SI tools from Zuken (Hot-Stage, Cadstar SI Verify) which do the job you are looking for very well proven by many customers - but let me express as well my honest opinion that most of the SI tools I know can do the task you are asking for - it depends on the PCB tool you are using, the level of integration in this PCB tool and the tool vendor support to enable you to do your tasks as quickly as possible and with shortest re-simulation loops. Just my opinion - feel free to contact me directly on further questions - regards Ralf Bruening Wednesday, October 6, 2004, 7:12:46 PM, you wrote: NS> Hello, NS> Is there a tool that would allow me to simulate post layout design with NS> greater flexibility to analyze nets, edit nets and see its effect on the NS> integrity of the signal?
