Answer Posted / manav rathi

function:
1:executes in zero stimulation time.
2:usually return a single value.
3:parameters of mode IN.
4:do not have wait statement.
5:function call state always concurrent.
procedure:
1:may or may not execute in zero stimulation time depending
upon whether it has wait statement or not.
2:may or may not retun a single value.
3:parameters of in,out or inout.
4:has wait statement.
5:procedure call statement may be cocurrent or sequential.

Calculate rise delay of a 3-input NAND gate driving a 3-input NOR gate through a 6mm long and 0.45m wide metal wire with sheet resistance R = 0.065 / and Cpermicron= 0.25 fF/m. The resistance and capacitance of the unit NMOS are 6.5k and 2.5fF. Use a 3 segment -model for the wire. Consider PMOS and NMOS size of reference inverter as 2 and 1 respectively. Use appropriate sizing for the NAND and NOR gate.
