In a compile, once QII sees a `define, it will be visible to all Verilog source files that are analyzed (parsed) later. This is actually a rather nasty behavior that's defined by the IEEE standard. In SystemVerilog, there's a concept of a compilation unit that can bre...
Note that by default,rstnwill not be included during compilation of the design and hence it will not appear in the portlist. However if a macro calledINCLUDE_RSTNis either defined in any Verilog file that is part of the compilation list of files or passed through the command line to the ...
Verilog-1995 has the conditional compilation directives: 'ifdef, 'else, 'endif, and 'undef. These directives control what portions of Verilog source code will be read in by a software tool. The simple if—else decision flow, however, can be awkward when there are multiple decisions to make....
In essence, it is a set of C libraries that provide two different things: Although much effort has been invested in the development of OpenCL compilers to make FPGA technology more accessible to people with a little background on it, many improvements are still necessary. The compilation of ...
