What should I pay attention to when I intend to create a pblock for Reconfigurable Partitions crossing Super Logic Regions (SLR)?
A Reconfigurable Partition's pblock that spans SLRs must be wide and high enough to grab the whole column of Laguna sites.
Failure to grab enough Lagunas can make the design unroutable.
The following DRC HDPR-54 will be triggered if the pblock fail to obey this rule:
An entire column of LAGUNAs within a clock region on either side of the SLR is required for this pblock. Please include a LAGUNA range for this pblock or keep the pblock within a single SLR.
In the following example design, all of the LAGUNA columns are not selected completely, which is illegal:
Note: The highlighted area is the LAGUNA site.
