An error that a package/class appears to have been referenced that has
|
||||
not yet been declared. According to IEEE 1800-2023 26.3, all packages
|
||||
must be declared before being used.
|
||||
|
||||
Faulty example:
|
||||
|
||||
.. include:: ../../docs/gen/ex_PKGNODECL_faulty.rst
|
||||
|
||||
Results in:
|
||||
|
||||
.. include:: ../../docs/gen/ex_PKGNODECL_msg.rst
|
||||
|
||||
Often the package is declared in its own header file. In this case add
|
||||
an include of that package header file to the referencing file. (And
|
||||
make sure you have header guards in the package's header file to prevent
|
||||
multiple declarations of the package.)
|
||||
|
||||
Never issued since version 5.038. Historically an error that a
|
||||
package/class appears to have been referenced that has not yet been
|
||||
declared. According to IEEE 1800-2023 26.3, all packages must be
|
||||
declared before being used. However, several standard libraries
|
||||
including UVM violate this, and other tools do not warn.

// DESCRIPTION: Verilator: Verilog Test module

//
|

// Use this file as a template for submitting bugs, etc.

// This module takes a single clock input, and should either

// $finish;

// on success, or $stop.
|

//
|

// The code as shown applies a random vector to the Test
|

// module, then calculates a CRC on the Test module's outputs.
