Function columns_verilog 

pub fn columns_verilog(sets: &[ColumnSet]) -> String

The columns of each set, with the modules they are built from: logos_column_decode_<name>, logos_column_core_<name>, logos_column_<name>, logos_column_array_<name> and logos_column_feed_<name>. A set’s core holds a block of any of its formats, its widths the set’s widest; with more than one format each module takes the job’s format as fmt, its place in the set, a block of fewer elements than the widest running with the units past it zero.
