openXC7 - no Bels remaining of type 'BUFR'

[harunkovacevic]

When using openXC7 (place and route step) we get an error in BUFR module, 'u_csi_rx_top.u_phy_clk.u_bufr' to be specific.

The message we received is:
ERROR: Unable to place cell 'u_csi_rx_top.u_phy_clk.u_bufr', no Bels remaining of type 'BUFR' 2 warnings, 1 error make: *** [Makefile:53: top.fasm] Error 255

This error arises from attempting to resolve this issue. We have now replaced BUFMR with BUFR, and the design was successfully tested in Vivado. @hansfbaier, @MikeReznikov Are there any indications on how we can put an end to this problem?

[chili-chips-ba]

Even if BUFMR and BUFR are internally the same component, they externally have different features, different look-and-feel, and are also treated separately in the corresponding vendor documentation.

We therefore want to track them as two separate, distinct issues.

I fixed it a while ago, I will submit the code tomorrow

@AdamLee7 send us the PR link or the branch link when you finish please :)

[kerimbavcic]

@AdamLee7 are there any news?

[hansfbaier]

@kerimbavcic The primitives-fixes branch has the BUFR support by @AdamLee7 already integrated.
But we need to test this branch more before merging, especially the LUTRAM changes there.
