4- Known bugs
 
-The usage of macros and defines may cause some errors.
-Using comments in switch case structures may cause errors. Specially
when using structures like:
case 1: //Comment here
case 2:
//Or comment here
case 3:
Better write it like this:
//Comment for 1, 2 and 3
case 1:
case 2:
case 3:
instructions . . .
instructions . . .
instructions . . .
 
A general rule would be: "Don't use comments in the same line of case or
in the inmediate next line. Use comments in the line before the case
statement"
 
5- For testing the application we recommend to use the systemcdes or the
systemcmd5 cores, both available at www.opencores.org.
