At certain points in the circuit, we need to constrain cells in advice columns to equal a fixed constant. Instead of defining a new fixed column for each constant, we pass around a single shared by all chips, that is included in the permutation over all advice columns. This lets us load all needed constants into a single column and directly constrain advice cells with an equality constraint. |
