// DESCRIPTION: Verilator: Non-cutable edge in loop
|
||
|
//
|
||
|
// This code (stripped down from a much larger application) has a loop between
|
||
|
// the use of ready in the first two always blocks. However it should
|
||
|
// trivially trigger the $write on the first clk posedge.
|
||
|
//
|
||
|
// This is a regression test against issue 513.
|
||
