Optimization
Specifying Tracking with Design Variables
The length of M1 and M2 is adjusted with:
.PARAMOPT E(M*,L)=(*, 0.1U, 1U)
The initial values specified on the instances are kept unchanged.
The following command adjusts lengths of M1 and M2, the initial values are both set to
0.35μm.
.PARAMOPT E(M*,L)=(0.35U, 0.1U, 1U)
The following sequence of examples affect model parameter VTH0:
.PARAMOPT EM(M2,VTH0)=(0.3, 0.1, 1)
Adjusts the parameter VTH0 of the model used by device M2. For this type of parameter the
initial value is ignored.
Using wildcards, the parameter VTH0 can be changed for both devices M1 and M2. This is
achieved with:
.PARAMOPT EM(M*,VTH0)=(*, 0.1, 1)
The commands:
and:
.PARAMOPT M(NMOD1.3,VTH0)=(0.3, 0.1, 1)
.PARAMOPT M(NMOD1.*,VTH0)=(0.3, 0.1, 1)
change the parameter VTH0 of the model NMOD1.3 and all models NMOD1.* respectively.
For this type of parameter the initial value is ignored.
