@ -115,6 +115,10 @@ Return a list of all bels at the give X/Y location.
Returns true if the given bel is a global buffer. A global buffer does not "pull in" other cells it drives to be close to the location of the global buffer.
### bool getBelIOB(BelId bel) const
Returns true if the given bel is a IO block.
### uint32\_t getBelChecksum(BelId bel) const
Return a (preferably unique) number that represents this bel. This is used in design state checksum calculations.
