RE: [sv-ec] compilation unit - class static variables

well, - yes you can workaround this by using packages
But dont you think that this is quite odd aproach and completly different
than ie  C++ one - and for sure can make a lot of confusion among SV users?
I was quite suprised when I realized that - and finding solution take me
some time.

This is exactly why we have packages.

 

pkgC.sv

package C_pkg;

`include "c.svh"

endpackage

 

Then change your `include's to import C_pkg::*;

Consider the code:

<c.svh)

class C;

    static int i;

endclass

 

<top.v>

`include "c.svh"

module top;

    initial C::i=123;

endmodule

 

<top1.v>

`include "c.svh"

module top1;

    initial #0 $display(C::i);

endmodule

 

Both file are compiled in separate compilation - so class C is compiled
twice into two separate compilation units. As far as i undertand the
description - we get two separate class C definition with two separate sets
of statics?

 

This way user cannot divide his design to part to compile them separetely
(ie if he has stucks on some lack of memory problems in sinngle compilation)
because C::i in first compilation and C::i in 2nd are totally different.
There is no way to workaround the problem... Why IEEE have decided to
describe it this way???

 

Am I right?
