Bug Report

Orimitsu Serizawa

I found the following bugs.

1. variables/objects declared below their reference point is not properly recognized in a class.

Example)

class my_class;  //int a; // O.K    function new();        a = 3;      //this.a = 3; //O.K    endfunction    int a; // Compile Errorendclass

The code above is complied normally if 'this' is not omitted.

2. Similarly, if the signal is declared outside the class inside a module, then, its declaration point must be above the class.

Example)

module tb; //int a; // O.K   class my_class;       function new();           a = 3;       endfunction   endclass   int a; // Compile Errorendmodule

3. In the same way, the signal must be declared above the class inside package.

Example)

package my_pkg; //int a; // O.K   class my_class;       function new();           a = 3;       endfunction   endclass   int a; // Compile Errorendpackage

Each complete test bench file is attached.

I hope these issues are resolved in the future release of DSim.

The LRM states (section 6.21):

A variable declaration shall precede any simple reference (non-hierarchical) to that variable.

It is possible that another vendor accepts your code; however, I cannot find any statement in the LRM that specifically allows this.
