expression, then the nested multiple-bit expressions exprand/or exprin the binary operator statement must be replaced by the appropriate incremental variable(s) to create an always statement that can be translated to generate a Verilog HDL statement that is equivalent to the conditional expression. ...
IF/CASE/COND (ICC) expressions occurring within the HDL program that are not recognized by Verilog HDL are categorized and accordingly translated to IF/CASE statements in Verilog HDL syntax. For ICC expressions that are part of a conditional or binary operator expression, a globally incremental ...
