Web"What I would like to simulate is, to set a process corner (ss/ff/tt..) and the apply local variation to the devices within each process corner." a set of three Monte-Carlo simulation sets is required using the respective "global" corner for each case (ss/ff/tt) using the "Mismatch" radio button selected. WebThe FF corner, for instance, is obtained by skewing both P and N devices to the fast corner. The TT corner is the center corner where wafers are normally produced (e.g. typical process parameters). In typically chip project schedule, corner lots should be produced just after tapeout or before releasing to production.
