Pin Location / Implementation Constraints
Pads can be assigned to a package pin
- The following example assigns a bus signal to pin 32
INST “QOUTɛ>” LOC = P32;
Physical Implementation may be controlled in the UCF file, such as:
FAST: Set fast I/O slew rate
Example: INST “$1I87/OBUF” FAST;
PART: Define part type to be used
Example: CONFIG PART=4005E-PQ160C-5;
