WebA net or reg declaration without a range specification is considered 1 bit wide and is a scalar. If a range is specified, the net or reg becomes a multibit entity known as a vector. Vector range specification contains two constant expressions such as: MSB: The most significant bit of constant expression, which is the left-hand value of the range. WebTo scalarize the vector ports when generating HDL code, either set the Scalarize ports parameter in the Configuration Parameters dialog box or set the ScalarizePorts property to on or dutlevel by using the hdlset_param or makehdl functions. When you set ScalarizePorts to dutlevel, only the vector signals at the DUT are flattened into scalars.
