Henry,
I think I've tracked this bug down to @xps_plb2opb/gen_mhs_ip.m, these
lines:
opb_name = blk_obj.opb_name;
opb_addr_start = blk_obj.opb_addr_start;
addr_size = blk_obj.addr_size;
opb_clk = blk_obj.opb_clk;
plb_clk = blk_obj.plb_clk;
if isempty(opb_clk)
opb_clk = 'sys_clk';
end
if isempty(plb_clk)
plb_clk = 'sys_clk';
end
blk_obj in this case definitely has no opb_clk or plb_clk attributes. Is it
supposed to? It seems like there should be a try catch block around the
attempts to access these members. I don't understand why this only shows up
in more complicated designs, is it because the plb_opb bridge is only
instantiated if there are several shared brams or registers?
I notice that these offending lines are new to the 10.1 version of things;
they are absent from the 7.1 version. Perhaps this is something to do with
ROACH?
I'm going to work around this way for now, but let me know if there is
something else going on before I commit a change.
Thanks,
Glenn
