WebMar 8, 2017 · If you are writing on a posedge, reading would be useful on a negedge. That would save one full clock cycle on a read operation. Negedge clock operation is also used in testbenches, to avoid race condition between DUT and Testbench, since both are driven at different clock edges. answered Mar 10, 2017 at 1:33.

WebOct 27, 2018 · In Verilog, I can use an always block and make it trigger on a positive or negative edge. Is it possible to trigger the block on both the positive and negative edge, and thus have it basically clocked at twice the rate? If so, does it incur a resource penalty?

WebDec 4, 2014 · Normally, designs work with rising edges (posedge). Falling edges (negedge) are needed for: multi cycle paths; a generic DDR description; other special I/O protocols; I think this is a stereotype: In Europe, a clock starts with a high period followed by low, whereas in America the clock starts with low followed by a high period.
