XC4000EX/XL/XV/XLT: How to accurately locate BUFGLS and BUFGE components
Description
Urgency: Standard
Keywords: TR,BR, BR, BL, LOC, XC4000EX, BUFGLS
Description The documentation currently explains there are only 4 locations constraints for the BUFGE, and the BUFGLS components, TR, TL, BR, BL. This information does not give the user accurate control of the placement of these buffers.
Solution
If you want more accurate constraints, use the site names of the BUFGLS that you find in EPIC when you click on these components.
The two locations in the TL loc are: "LOC = BUFGLS_WNW" for the one in the left or "LOC = BUFGLS_NNW" for the one in the top.
The two locations in the BL loc are: "LOC = BUFGLS_WSW" for the one in the left and "LOC = BUFGLS_SSW" for the one in the bottom.
The two locations in the BR loc are: "LOC = BUFGLS_ESE" for the one in the right and "LOC = BUFGLS_SSE" for the one in the bottom.
The two locations in the TR loc are: "LOC = BUFGLS_ENE" for the one in the right and "LOC = BUFGLS_NNE" for the one in the top.
