What does "|" mean here: "assign IntxReq_o = |irq_reg & intx_mode;"
I saw this expression today:
assign IntxReq_o = |irq_reg & intx_mode; noticing there is a "|" right ahead of "irq_reg". I am familiar with "|=", but never saw "=|" before. Anyone knows? Update: It is reduction OR. Since irq_reg has multiple bits, the operator yields an OR result of all bits together. Apparently, I was using a much more labored way for a long time.
