title: printing "still alive message" only once for multiinstance bindings in system verilog
body: <p>I have the following problem I like to solve. I use bindings to bind system Verilog assertions to the RTL. To make sure that the binding is enabled I added at the beginning of the binding code a "sva xyz binding is alive" message.
  This binding will be instantiated many times because the block I bind my assertion to is used many times in the RTL. Now I got as many "is alive" messages as instantiated blocks, which spams the log file of the simulation.</p>
  
  <p>Is there a way to prevent this ? The only way I have in mind is using a toplevel variable and access this variable via a hierarchical access, but this is just an ugly workaround.</p>
  
  <p>This is the message I added at the beginning of my sva binding code</p>
  
  <pre><code>   `ifndef _ALARM_FLAG_SVA_ON
         `define  _ALARM_FLAG_SVA_ON
         initial begin
           $display ("-I-: SVA binding for ALARM_FLAG is alive.");     
         end
      `endif
  </code></pre>
  
  <p>The problem here is that I read the file only once, which means that the ifndef is correct for all multiple instance bindings.</p>
  
  <p>thanks
  rth</p>
