- SystemVerilog Macros - systemverilog. io
Macros are code snippets created using the `define compiler directive They essentially have 3 parts - a name, some text and optional arguments `define macroname(ARGS) macrotext
- SystemVerilog `define Macro - ChipVerify
SystemVerilog enhances Verilog’s `define text substitution macro by permitting the inclusion of certain special characters in the macro text In Verilog, quotation marks (") can be used in a define macro, but the text within the quotation marks is treated as a literal string
- `define macros usage - SystemVerilog - Verification Academy
You can use parameterized macro but you cannot use a variable while calling it `define VAR_LANE(x) 8'h``x bit [7:0] local_var1 = MEMORY[`VAR_LANE(0)]; or `define VAR_LANE0 8'h07 `define VAR(x) `VAR_``x bit [7:0] local_var1 = `VAR(LANE0);
- Defines and Macros - SystemVerilog Tutorial - Verification Studio
The `define directive allows you to create macros A macro in SystemVerilog is a named piece of code that is defined to do a particular task Once you've defined a macro, you can use it elsewhere in your code The define directive works like this: ` define macro_name macro_body Here's an example: ` define SIZE 32 reg [` SIZE-1: 0] data;
- verilog - Defining different parameter value for simulation and . . .
Yes You can set a macro from the command line in any simulation using the +define plusarg, eg: +define+SPI_RATE=2_000_000 Then somewhere in your code, you can say parameter SPI_RATE = `SPI_RATE; And in your synthesiser there will be a mechanism for setting the value of a macro: read the instructions for your synthesiser
- SystemVerilog Parameters and `define - Verification Guide
`define Macro The `define compiler directive is used to perform global macro substitution and remain active for all files read compiled after the macro definition It will available until another macro definition changes the value or until the macro is undefined using the `undef compiler directive
- System Verilog Macro: A Powerful Feature for Design Verification Projects
The directive “`define” creates a macro for substitution code Once the macro is defined, it can be used anywhere in a compilation unit scope, wherever required It can be called by (`) character followed by the macro name
- SystemVerilog compiler directives - VLSI Verify
SystemVerilog `define macro The SystemVerilog macro is a compiler directive that substitutes itself in the code with a defined context In simple words, wherever macro is used, it is replaced with macro context and gives compilation error in case of misuse
