Dear Mega star,
You have given the answer ,fine,
But i need little clarification
In case of Tclk>=Tpd reg1+Tpd (combo2)+Ts (reg2)=2+5+4=11
In this case the Clk has to propagate from R1 so Tpd (reg1)
then it has propagate thro Combo2 So Tpd (combo2)
Then Setup time of Reg2 so Ts (reg2)
My question is y did u consider Ts of Reg1, it is similar to Reg2 side since clk is propagating into Reg2 too,
2) In Th calculation you have considered as Tcd combo1+Th reg1=1+2=3
I did not understand, pls help me
