The BitBasher Block
The BitBasher block provides a textual method, based on Verilog syntax, for working with the signals at the bit
level. This block supports concatenation and slicing if the input signal to create an output. It also allows for
augmentation with constants. The BitBasher block supports up to 4 outputs that are inferred by the expressions
