[IBIS-Users] Inclusion of RLGC package info in IBIS

Hello all,

I have to include package data which is in the RLGC matrix format (derived from Hspice) in IBIS files. There are different sets of matrices specified for the different sections like breakout2, via and the transmission line as shown below. Also the length parameter is given for package trace.

Seg 1(Break out )    Seg 2(Short trace)     Seg 3(Via)     Seg 4 (Package long trace)  Seg 5(Via and Solderball)

My problem is :

1> The package model section of the IBIS file does not provide an option to include RLGC matrices for multiple sections.

2> Also there is no keyword to specify the length for the traces when the "model data" option is used. This option is provided only when "Number of sections" is used. But since "Number of sections" and "model data" option is mutually exclusive I cannot use this.

Hence how do I go about including multiple sets of matrices in the IBIS file?

Looking forward for your reply.

Thanks,
