Thanks Brendan. I think adding ISSUE_Q_SIZE to ooo_core.conf. Unfortunately no luck. Here is the section of issue queue. The next instruction is being inserted to slot 27. This happens soon after some instructions are flushed. I have set the issue queue size as 100. IssueQueue: count = 27: uop 16: V - - 13 ??? ??? ??? uop 17: V - - 16 ??? ??? ??? uop 18: V - - 17 17 ??? ??? uop 19: V - - 17 17 17 ??? uop 20: V - - 13 ??? ??? ??? uop 25: V - - 20 ??? ??? ??? uop 32: V - R ??? ??? ??? ??? uop 39: V - - ??? ??? ??? 38 uop 40: V - - 39 ??? ??? ??? uop 41: V - - ??? ??? ??? 38 uop 43: V - - 40 40 13 ??? uop 44: V - - 43 43 ??? ??? uop 45: V - - 44 44 ??? ??? uop 48: V - - ??? ??? ??? 42 uop 49: V - - ??? ??? ??? 42 uop 50: V - - ??? ??? ??? 42 uop 51: V - - ??? ??? ??? 42 uop 53: V - - ??? ??? ??? 42 uop 55: V - - ??? ??? ??? 42 uop 56: V - - 55 ??? ??? ??? uop 59: V - - 56 ??? ??? ??? uop 61: V - - 48 ??? ??? 42 uop 62: V - - 50 ??? ??? 42 uop 63: V - - 48 ??? ??? 42 uop 64: V - - 63 ??? ??? ??? uop 65: V - - 48 ??? ??? 42 uop 66: V - - 64 ??? ??? ??? uop 65535: V - - 65535 ??? ??? ???

I'm not sure why that causes an assertion, but if you look in config/ooo_core.conf you'll see that you can define parameters there. I added ISSUE_Q_SIZE to the list and it worked fine, so I would suggest you modify it there instead.

However when I did it the assert(!bit(valid, slot)) of insert in IssueQueue (ooo-exec) is failing. When I printed out the issue queue I found out that there is a uop with tag value 65535. Is there something else which I should change when I'm changing OOO_ISSUE_Q_SIZE?
