《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
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; // Declare a 1-bit logic type variable initial begin $display ("my_data=0x%0h en=%0b"...
set_param('svdpi_BitVector','DPIFixedPointDataType','BitVector'); Generate SystemVerilog DPI Component In the "svdpi_BitVector" model, right click the SineWaveGenerator block, and select C/C++ Code -> Build This Subsystem. Click Build in the dialog box that appears. ...
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 ...
These bugs may be the result of erroneous or incomplete user instructions to the synthesis tools, ambiguities and misunderstandings of SystemVerilog or other RTL languages, wrongly documented design libraries or components, or occasional errors in the synthesis tools themselves. Thus, nearly everyone ...
In SystemVerilog, the standard 2-valued data type is bit which can take on value 0 or 1. Digital circuits exhibit traits that cannot be captured with a 2-valued abstraction, however. Just think of transients, indeterminate states following power-up, three-state outputs, multiple buffers ...

The logic is not a concept defined in HDL but is a heuristic introduced by the AMD Vivado™ simulator. A Verilog object is considered to be of logic type if it is of the implicit Verilog bit type, which includes wire and reg objects, integer, and time.
