@@ -15,7 +15,7 @@ Traditionally, larger multiplexers are built using trees of smaller multiplexers
 Multiplexers trees lead to large power and timing constraints that limit FPGA performance. FPGA fabrics use complementary pass gate logic (CPL) to replace multiplexer trees with single level inverted transmission gate derived multiplexers, as illustrated below:
