PowerPlan : basic introduction
Hi All, Hope you have gone through posts related to Flooroplan and Synthesis. Lets understand importance of PowerPlan in ASIC design flow. PowerPlan In older Technology nodes, main priorities were given to Timing and Area because these parameters were dominant over power . however in lower nodes, as devices are shrinking there are more numbers of devices in same area. Also to supply power to these smaller devices, Power supply also becoming smaller over a time ( consider mobile batteries. its size keep reducing in last 10 years..!!! and also supply power is also reduced i.e. in older nodes, supply voltage in range of 1.5-2 V while it is drastically reducing now a days within 0.6-0.8 range). in lower nodes, to address complex timing challenges power consumption is increasing hence in power is more dominant over area and timing. Terminologies Power PAD : it is source from where chip get the power from external world. for wire-bounding Technology,...
