SystemVerilog 引入了一种全新的四态数据类型,称为logic,它可在过程块和连续assign语句中驱动。但对于含多个驱动程序的任一信号,您都需要为其声明 net 类型(如wire),这样 SystemVerilog 才能解析最终值。 logic module tb; logic [3:0] my_data; // Declare a 4-bit logic type variable logic en; // Dec...
《SystemVerilog vs Verilog in RTL Design》ByPong P. Chu, Chapter 3.1logicDATA TYPE Verilog‐2001 divides the data types into a "net" group and a "variable" group. The former is used in the output of a continuous assignment and thewiretype is the most commonly used type in the group. T...
19139 - XST - XST creates incorrect logic when using signed data types in Verilog Description XST will improperly sign extend signed data type signals when signed and unsigned data type operands are used together in an operation: output [5:0] O; input [5:0] in1; input signed [3:0...
The SUPERLOG language, which was the predecessor to SystemVerilog, created the logic datatype that was originally slightly different from reg in that it allowed a single continuous assignments to logic variables in place of any procedural assignments. With only one driver, no strengths or...

level like we have done previously. It would simply take too long to develop applications which can leverage the resources provided by the programmable device at the gate level. In the place of developing by using logic equations, we use Hardware Description languages (HDL) such as Verilog or ...
