A primary goal of SystemVerilog is to enable modeling large, complex designs more concisely than was possible with Verilog. This chapter presented enhancements to the procedural statements in Verilog that help to achieve that goal. New operators, enhanced for loops, bottom-testing loops, and unique...
1.these statements have a similar effect to the assign-deassign pair,but a force can be applied tonets as well as to variables. 2. the left-hand side of the assignment can be a variable, a net,a constant bit-select of a vector net, a part-select of a vector net ,or a concatenta...

It resembles in many ways programming languages that declare a set of variables and use a sequence of procedural statements to execute certain computations or algorithms. While variables may be declared along with parameters in the module body, the procedural statements in Verilog-A are encapsulated ...
