Output Stability Calculation
When does output data need to be stable?
- Data must be stable in order to meet the setup requirement for IC3
- How long must the data be stable before data is latched in IC3?
- Tstable = Tc3 + Tpad + Tnet + Tc4 + Tsetup + TCD
- TCD is the delay through the clock distribution network
Tstable = Tc3 + Tpad + Tnet + Tc4 + Tsetup + TCD
