# While the code below looks messy, it was taken directly from a vivado example
# See here (https://www.xilinx.com/support/answers/66386.html)
# See also this link (https://github.com/lowRISC/opentitan/pull/8138#issuecomment-916696830)
# for a thorough explanation of why such a custom placement helps.
# Note the placement location was not chosen through any systematic means, but through trial
# and error, it may become necessary in the future to tweak this if other congestion
# issues arise.
