SPEF File Structure
The following section contains the parasitics, grouped by net name. A net section begins by the
net name and the total net capacitance, and ends with a *END. This section contains subsections
about connections, capacitances, resistors, and inductions. They are defined as follows:
*D_NET N1 0.000153
*CONN
*P N1 I *L 0.1 --> port in the net for external connection
*I N2:P1 I *L 0.001308 --> instance pin in the net for internal connection
*CAP
1 N1:1 0.000084
2 N1 0.000032
3 N2:P1 0.000037
*RES
1 N1:1 N1 0.353405
2 N1:1 N2:P1 10.847200
*INDUC
1 N1 top 0.000001
*END
