Spectre Example
The following example illustrates an instantiation of a D2A interface element, CML3_d2a,
from the
ieLib
library. Assume that it has the following properties.
Because the macro property is not empty, the instance is formatted as a macro model.
The CDF simulation information for this instance is as follows:
The propMapping value maps CDF properties to Spectre properties. For example, the CDF
property
d2a_tr
maps to the Spectre property
rise
. Therefore, the Spectre property values
are as follows:
