WebFeb 8, 2015 · \$\begingroup\$ Can you share the test-bench and tell us what simulator and version you are using. If your design is only one flip-flop, blocking vs non-blocking assignment shouldn't be an issue. My guess … WebJul 25, 2008 · 7. Trophy points. 1,298. Activity points. 1,902. hi in ur case,if u use both blocking or non blocking in RTL, the synthesis tool will produce a D flip flop, thats sure. But it is recommended to use Non Blocking for Sequential Design. And Blocking for combinational. Since Flip flop is sequential use non blocking.
