[PDF File]Introduction to SystemVerilog
https://info.5y1.org/systemverilog-interface_1_c3ea77.html
This chapter describes a SystemVerilog “program” and its differentiation with SystemVerilog “module.” Among other aspects, it describes how race can be avoided between a testbench and a DUT. Chapter 11: SystemVerilog “interface” This chapter discusses nuances of SystemVerilog “interface,” including modports

System Bus Interface 2 SUNY – New Paltz Elect. & Comp. Eng. Advantages of Bus Interface • Allows the number of signals to be grouped together and represented as a single port • The single port handle is passed instead of multiple signal/ports. • Interface declaration is made once, and the handle is passed across the modules/components.

Abstract— The interface is perhaps the most versatile part of the SystemVerilog language when it comes to verification. The interface is where static meets dynamic, abstract meets concrete, the rubber meets the road, the glue that holds a verification environment together… I The interface is the main communication mechanism between
