| | | | | | | | | | | | | | | | | | | | | | | | 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. Signed-off-by: Maciej Dudek <mdudek@antmicro.com>
