When I generate a system with the BSB wizard it will not always pass the memory test. But when I change something it generates sometimes a system that actually run. I think there is a problem with the clock buffers.
I get the warning:
Place:619 - This design either uses more than 8 clock buffers or uses more than 4 DCMs or has clock buffers locked to side-BUFG sites or has DCMs locked to side-DCM sites.
Route:455 - CLK Net:bscan_update may have excessive skew because 2 CLK pins and 0 NON_CLK pins failed to route using a CLK template.
Route:455 - CLK Net:sys_clk_pin_IBUFG may have excessive skew because
1 CLK pins and 0 NON_CLK pins failed to route using a CLK template.
And more of these.
I use EDK 9.1.02i.
Is there something I can do about this, or is it just due to insufficient resources?
