M1.3/1.4 and FPGA Express: M1 Constraints, LogiBLOX, and modules within FPGA Express


Keywords: constraints, cst, FPGA Express, FPGA, Express, timing, location,

Urgency: standard

General Description:
This solution is an overview of using M1 constraints with FPGA Express as the
top-level design tool. Constraints that FPGA Express can directly apply will
be documented. Information on how to reference instance names in XNF files
from FPGA Express will be documented; when constraints are needed that FPGA
Express cannot apply, a UCF file referencing instance names in the XNF file
will be made. Similarly, information on how to reference the instances inside
LogiBLOX RAM/ROM modules will also be provided for creating UCF constraints.
