i am using RLOC statement as ..
//synthesis attribute rloc of d1 is X12Y11
As far as i understand, these X-Y co-ordinates specify the Slice number.
My first question is - how do i specify which of the two flip-flops(in one slice) to use?
.. i was going thru the documentation, where i noticed RLOC_RANGE option, has anybody used this option.
i tried it as -
//synthesis attribute RLOC_RANGE of d1 is X0Y0:X2Y2
the MAP failed and reported,
ERROR:Map:10 - RLOC_RANGE attribute on FD symbol "d1" (output signal=t) must be on the start of a set.
What am i doing wrong?
