4.1isp3 IBISWriter - The values for package capacitance (C_pkg) and inductance (L_pkg) are swapped

Description

Keywords: IBIS, Writer, IBISWriter, simulate, simulation, Virtex-II, L_pkg, C_pkg, inductance, capacitance, package, parasitic, model, I/O, IO

Urgency: Standard

General Description:
When a design-specific IBIS model is created, IBISWriter swaps the values for package capacitance and inductance:

R_pkg...........0.1...........0.1..........0.1
L_pkg............0.5pF.......0.5pF......0.5pF
C_pkg............0.8nH......0.8nH......0.8nH

(Capacitance should be measured in Farads, inductance in Henries.)

Solution

This problem is fixed in ISE 4.2i, which will be released in early March, 2002.
