FPGA routing matrix

An FPGA device contains flexible programmable routing matrix which is used to connect logic blocks with each other. There are various type of connection lines in FPGA:

  1. long lines are used to connect distant logic blocks,
  2. short lines connect neighboring blocks with each other,
  3. dedicated clock trees are used to distribute synchronization signals (these lines have large fanout and little skew and jitter).
  4. dedicated set/reset lines are used to reset all flip-flops in the FPGA.
