Thank you all for the reply!!!! Yes i understand for analog we check the polygons for parasitic R and C. But i don't understand "parasitic interconnect" in digital. I mean take an analog layout wen we lay the transistor we get some parasitics. Also when we do routing to connect different cells the wires/ interconnect (metals) cause parasitics. So is this the same interconnect parasitic you are talking about in digital too. Like the R and C in analog.
Also could you kindly explain what does it mean by "parasitics inside the cell". Meaning like what does this parasitic represent other than R and C. becoz take analog or digital, in the end all are made of the metal layers that make up a transistor and interconnecting metals. So what kind of parasitic is der other than R and C for digital cells??? Kindly help pls!!!
