I have to setup a chip with 5 completely separated cores. Each core has its own vcc_core/io and vdd_core/io ind i/o pins.
But the actual voltage of all cores is 1.8V. For testing only one core should be active at a time.
Can I do this just with connectGlobalNet or is this more like a multi supply voltage flow with a single volate?
If there is some documentation about this topic, please give me a hint. The UserGuide didn't cover this topic.
Ok, this should be pretty easy then. You might want to look at globalNetConnect -module to assign the different sources to the different core hierarchies.
For sroute, try putting placement blockages between the core fences. That should stop the followpin generation from happening between fences. If I've misunderstood, please post a picture - I'm sure we can get the tools to do what you want here.
