[Synth 8-97] array index 3 out of range [ipbus_ctrs_ported.vhd:84]

Closed this issue 5 years ago · 3 comments

When I use ipbus_ctrs_ported with N_CTRS = 4, Vivado gives error of "array index out of range" on line 84 of ipbus_ctrs_ported.vhd. In the code "stb(N_CTRS * CTR_WDS - 1) = '1' " is obviously out of range for N_CTRS = 4 and CTR_WDS = 1 provided stb is defined std_logic_vector(0 downto 0); in line 76.
How do I fix this problem? Thanks

Hi,

I've fixed this bug on branch bug/122-counter-slaves. Can you please try checking out that branch, and let me know if you still see any other problems?

Cheers,
Tom

Hi @tpsubedi ,

Thanks for confirming that the slave is working fine following the bugfix. I've now merged the bug/122-counter-slaves branch into the master, and created a v1.5 tag [1]. So I recommend using the v1.5 tag for future FW builds.

Cheers,
Tom
