Advanced Wreal Modeling Features

To provide some benefits to the wreal construct, Cadence has made significant extensions, beyond the Verilog-AMS LRM restrictions. These extensions enable support for:

• Electrical to wreal and wreal to electrical connect modules

• Connecting wreal nets hierarchically to wires and coercing the wires to become wreals

• wreal arrays, similar to busses, that groups multiple real values into a single, indexible entity

• wrealXState and wrealZState

• Resolution function for wreal nets with multiple wreal drivers using the -wreal_resolution command-line option

• wreal as an independent variable in the $table_model function

• Connecting a wreal to a VHDL real signal or SystemVerilog real variable

• Automatic “type-casting” to wreal when a wire is hierarchically connected to a wreal, SystemVerilog real variable, or VHDL real signal
