CummingsSunburst Design, introduced an enhanced and abbreviatedmethod to declare module headers, Ports and data Accellera SystemVerilog effort will further enhanceVerilog design by abbreviating the capability toinstantiate modules with implicit port connections andinterface Types . These capabilities and additionalcomplimentary enhancements are detailed in this IntroductionTo declare, or not to declare, that is the question!Verilog-1995[1] had verbose and redundant portdeclaration requirements. Verilog-2001[2] introduced the ANSI-C -style enhancement to remove port declarationredundancy from the Verilog language.
HDLCON 2002 3 SystemVerilog Ports & Data Types For Simple, Rev 1.1 Efficient and Enhanced HDL Modeling Figure 2 - Test-module intended logic The Verilog code of Example 4 was intended to implement the circuit of Figure 2, but two common mistakes were made: (1) the output of the buffer was labeled outl (letter “l”) instead of out1 (digit 1), and
