Abstract:
Some embodiments provide support for real number modeling in SystemVerilog by defining built-in nettypes with real data type and resolution functions natively in SystemVerilog and allow a simple path for porting Verilog-AMS wreal modeling to SystemVerilog modeling. Some embodiments provide support for incompatible nettypes and for net coercion in SystemVerilog. Some embodiments provide support for SystemVerilog reals net connecting to electrical nets and support for SystemVerilog real signals connecting to Verilog-AMS wreal signals. Some embodiments combine the strengths of Verilog-AMS and SystemVerilog languages to build a solution for value conversion between incompatible nets and an effective way to configure, simulate, or verify mixed-signal designs that are written in SystemVerilog language.
