Problem with JBits 3.0 Tutorial
Hi Folks,
I have been working my way through the tutorial that is supplied with
the JBits 3.0 SDK, and have encounter the following problem when
running
the TracerExample.java
(<JBITS_HOME>\src\com\xilinx\demo\tracer\TracerExa mple.java)
Exception in thread "main" java.lang.NullPointerException
at com.xilinx.JBits.Virtex2.Wire.exists(Wire.java:130 )
at com.xilinx.JBits.Virtex2.Pin.<init>(Pin.java:86)
at com.xilinx.demo.tracer.TracerExample.main(TracerEx ample.java:48)
Which seems to point to the following
............
/* set the JBits object in the Wire class */
Wire.setJBits(jbits);
/* Get the lookup instance */
Lookup lookup = Lookup.getLookup();
/* Instantiate a RouteTracer */
RouteTracer tracer = new RouteTracer(lookup);
/* Trace CLB(0,0,XQ0) and print out the net */
Pin src = new Pin(Pin.CLB, 0, 0, Wire.XQ0); <-- This is line
48
.............
And I was wondering if anyone has came across the same problem and
hopefully found a solution which they could share with me, As I can't
find an pointers to the solution on google.
Any help great fully received,
Regards,
Paddy
