Thanks for reporting. Is there an easy way to reproduce this?

Subject: [gem5-users] SimpleDDR3 failing on an assertion with default parameters
Hi all,
I'm running the SimpleDDR3 memory with default parameters and one of my
benchmarks is failing on a panic/sanity check. I was wondering if any knew of
any issues with the default DDR3 parameters or if this sanity check might be
overzealous?
Here's how I've configured the memory:
physmem = SimpleDDR3(range = AddrRange('1GB'), zero = True)
Here's the error:
panic: Got 4 activates in window 36250 (5351656042250 - 5351656006000) which is
smaller than 40000
@ cycle 5351655344750
[recordActivate:build/ARM/mem/simple_dram.cc, line 830]
Memory Usage: 1796052 KBytes
Program aborted at cycle 5351655344750
I'm generating a trace now to try to diagnose why the number of activates were
not properly limited, but I'm rusty on reading DDR timing info.
Thanks for any help.
