Hi all,
Now, I am trying to using Jroute2 to do some routing things. But I am blocked by some questions.
1\ find all the connections to an output of a slice, for example, all the connections to CLB(4,0,S0_XQ), 2\record all the sinks of the src:CLB(4,0,S0_XQ) 3\ using reverseUnroute to unroute all these connections. 4\ rebuild all the connections to a new src CLB(4,2,S0_XQ) I have done the first three steps successfully, but in the forth step, I find something unusual: there used to be a connection form CLB(4,0,S0_XQ) to CLB(4,3,S1_F1), but after I rebuild the connection to a new src CLB(4,2,S0_XQ), the connection turn out to be from CLB(4,2,S0_X) to CLB(4,3,S1_F1). All I did was changing the src pin(from CLB(4,0,S0_XQ) to CLB(4,2,S0_XQ)),I have never change the resource. I want to know what happened? Why does the connection change by itself?I am looking forward to receive you reply! Many thanks and best regards!
Sincerely Nicky
