Merge pull request #825 from antmicro/chain_swap_fix 
Fix chain swap
 2021-09-23 14:10:46 +01:00

8c97cbe341 Fix chain swap 
Issue was due to dest_bels being not cleared between clusters unbindes, causing
newly bind bels to be unbinded and having their old bel value changed to new bel value.
Then when swap failed 2 cells were being bind to a single bel.

I tested leaving dest_bels in the function scope and moving it to the loop scope.
Code with dest_bels in the loop scope was faster than leaving it in the function scope,
and checking if the cell is in the processed cluster.

a519341112 Fix bug in router2 where router may give up too early. 
Was introduced in #612.  The logic before was intended to prevent the
router from terminating early when not using a bounding box, but the fix
in #612 simply removed that, meaning that the router might terminate
early incorrectly.  The solution here is to only use the toexplore
hysteric once a solution is found.
