Using Spice and CDL For Netlist Driven Layout Generation
Ex 11 : InstTree = Xibuf2@IBUF / Xinv4@IBUFTWO / m6@MIV
Parameter = L
Value = 30U
Reason : Fet m6 specifies L = P4. P4 can be passed into m6. Xinv4 specifies P4 = WW. WW cannot be passed into Xinv4. Further WW does not exist at the cell level nor the file level for Xinv4. However, WW = 30U is specified in MIV, which is the master of Xinv4.
Parameter Scaling
There are specific, named, fet level parameters that are scaled based on the scaling factor that may be specified on theOPTION. statement. The scaling factor used is the one that was specified for the file in which the fet resides. The parametersL, W, PS, and PD are scaled, with the rule being that the parameter value is multiplied by the scale factor. Also scaled are AS and AD , with the rule being that the parameter value is multiplied by the scale factor squared.
Note: Character case is not considered when determining whether or not to scale a parameter. For example, the parameters l, as, and Ad, at the fet level, are scaled
Ex : Scaling
Consider the following partial netlist.
File : s1.sp
*
.option scale = 2.0
.param P1=1U
.include '/net/mycds/spice_files/s2.sp'
.subckt IV A Q P2= 2U
m1 vdd A B vdd TP W=P1 L=P2 AS=5U File : s2.sp
*
.option scale = 3.0
.subckt IB I O

Xiv1 I A IV P2=4U
For the instance tree Xiv1@IB / m1@IV, to take scaling into account;
■ the parameter W resolves to 2U because W = P1 * (scale from s1.sp) = 1U * 2.0 = 2U.
■ the parameter L resolves to 8U because L = P2 * (scale from s1.sp) = 4U * 2.0 = 8U.
Note that P2 is passed into m1 from Xiv1.
■ the parameter AS resolves to 20U because AS = 5U * (scale from s1.sp)**2 = 5U * 4 = 20U.
