[myhdl-list] Python bool type used as constant

[Josy B. <jo...@c-...>]

Hi all,

The following code:
def ramreader( Clk, Reset , ... , WRAP_AROUND ): # WRAP_AROUND is a Python 
bool constant
...
   @always_...
   def f():
      ...
      if not  WRAP_AROUND :

gets converted to:
      if (not '1') then

which is invalid VHDL ...

A work-around is to bring the constant to the highest level and 
conditionally generate the two cases:

def ramreader( Clk, Reset , ... , WRAP_AROUND ): # WRAP_AROUND is a Python 
bool constant
...
   if not  WRAP_AROUND :
      @always_...
      def f():
         ...
   else:
      @always_...
      def f():
         ...

Now we have duplicated the code and the maintenance

Regards,

Josy
