• If DEVICE does not include an output port name, VCS assigns
the value to all the pin-to-pin delay (tpd) generics in the cell. For
example, if the DEVICE construct is
DEVICE (1:2:3)
VCS assigns the timing value to all the following generics:
tpdIn1_Out1_R, tpdIn2_Out1_R, tpdIn1_Out2_R,
tpdIn2_Out2_R, tpdIn1_Out1_F, tpdIn2_Out1_F,
tpdIn1_Out2_F, and tpdIn2_Out2_F.
