Power domains or not?

schnufff

Hi all,

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.

  • It almost sounds like you can just use globalNetConnect, but when you say that only one core should be active at a time, that implies domains controlled by power-switch cells, which is more complicated. There is a Low Power Design chapter in the EDI user guide, have you reviewed that? If you need further info, search for Low Power on support.cadence.com. There will be some other documentation there.
