Re: 8B/10B code patterns.
Benny - does this help, or do you want something else? If needed, the lookup tables can be built in the "other direction".
The first tab lists +/-10B characters and their binary and 8B equivalents.
The right tab can be used to build a pattern. Simply list out the 10B D characters and copy down the other columns to fill in the rest of the data. The 10B Hex column can be re-written if you need a different form for BERT loading.
