I actually found that too and reverted it back to the the original
bus_clk/rst and ce_bus/clk such as below:

noc_block_delay_fifo inst_delay_fifo (
.bus_clk(bus_clk), .bus_rst(bus_rst),
.ce_clk(ce_clk), .ce_rst(ce_rst),

.i_tdata(ce_o_tdata[0]), .i_tlast(ce_o_tlast[0]),
.i_tvalid(ce_o_tvalid[0]), .i_tready(ce_o_tready[0]),
.o_tdata(ce_i_tdata[0]), .o_tlast(ce_i_tlast[0]),
.o_tvalid(ce_i_tvalid[0]), .o_tready(ce_i_tready[0]),
.debug(ce_debug[0])
);

I am unsure of why I changed that in the first place, but I think it may
have been originally to route the ce_clk/rst to clk/rst as in .clk(ce_clk),
.reset(ce_rst).

For my user code in the source file, should I just use ce_clk rather than
generating a new clk?

Thank you,

Adam

Why have you commented out bus_clk/rst and ce_clk/rst in favor of using
clk/reset? And where are clk/reset/clear being generated? What is being
used as bus_clk/rst in your block's noc_shell?

Nick,

Haven't heard back from you yet and was just wondering if you were able to
give it a look.

I have a feeling that i may have not instantiated the block correctly in
rfnoc_ce_auto_inst.v, so I am currently attempting to figure out what might
be wrong. Any help or insight into this scenario would be much appreciated.

Thank you,

Adam

Yeah, ok. It's that multiple driver that's the problem. Can you post the

That all looks ok to me. Does it successfully generate a bitstream?

There will virtually always be warnings, even some "critical" ones, in any
sufficiently complex FPGA project.

The use of Gnuradio will not affect the FPGA design at all. If you supply

Hello all,

I am trying to design an RFNoC block using Vivado 2015.4, but I keep
running into synthesis and implementation critical warnings.

Can you explain to me step by step how to instantiate a working rfnoc
block WITHOUT using gnuradio? It seems that most information I am finding
online include the use of gnuradio.

I believe I have my environment setup correctly and I am calling the
noc_shell and axi_wrapper modules within my blocks. However, the errors I
am receiving are not stemming from the user code I have written, instead
the errors are coming from various design sources within the e310 fpga
source code.

Please help. Thank you

ce_clk is there for you to use as your compute engine clock. If you don't
have a very good reason to generate and use another clock, you should use
that one.

I actually found that too and reverted it back to the the original
bus_clk/rst and ce_bus/clk such as below:

.ce_clk(ce_clk), .ce_rst(ce_rst),

.i_tdata(ce_o_tdata[0]), .i_tlast(ce_o_tlast[0]),

.o_tvalid(ce_i_tvalid[0]), .o_tready(ce_i_tready[0]),
.debug(ce_debug[0])
);

I am unsure of why I changed that in the first place, but I think it may
have been originally to route the ce_clk/rst to clk/rst as in .clk(ce_clk),
.reset(ce_rst).

For my user code in the source file, should I just use ce_clk rather than
generating a new clk?

Why have you commented out bus_clk/rst and ce_clk/rst in favor of using
clk/reset? And where are clk/reset/clear being generated? What is being
used as bus_clk/rst in your block's noc_shell?

I have a feeling that i may have not instantiated the block correctly in

be wrong. Any help or insight into this scenario would be much appreciated.

That all looks ok to me. Does it successfully generate a bitstream?

There will virtually always be warnings, even some "critical" ones, in any
sufficiently complex FPGA project.

The use of Gnuradio will not affect the FPGA design at all. If you supply

Hello all,

I am trying to design an RFNoC block using Vivado 2015.4, but I keep
running into synthesis and implementation critical warnings.

Can you explain to me step by step how to instantiate a working rfnoc
block WITHOUT using gnuradio? It seems that most information I am finding
online include the use of gnuradio.

I believe I have my environment setup correctly and I am calling the
noc_shell and axi_wrapper modules within my blocks. However, the errors I
am receiving are not stemming from the user code I have written, instead
the errors are coming from various design sources within the e310 fpga
source code.

Please help. Thank you

On a side note, this is a good time to mention that learning to simulate
RFNoC blocks with the excellent and comprehensive testbench framework
Jonathon put together is the single most effective way to write better
RFNoC blocks, faster. This kind of error would be caught almost instantly
in simulation, instead of waiting N minutes for Vivado to synthesize and
implement it.

It is absolutely worth your time to start working with the testbench now,
instead of deferring because your block almost works.

ce_clk is there for you to use as your compute engine clock. If you don't
have a very good reason to generate and use another clock, you should use
that one.

I actually found that too and reverted it back to the the original

.ce_clk(ce_clk), .ce_rst(ce_rst),

);

I am unsure of why I changed that in the first place, but I think it may
have been originally to route the ce_clk/rst to clk/rst as in .clk(ce_clk),
.reset(ce_rst).

For my user code in the source file, should I just use ce_clk rather than
generating a new clk?

Why have you commented out bus_clk/rst and ce_clk/rst in favor of using

That all looks ok to me. Does it successfully generate a bitstream?

There will virtually always be warnings, even some "critical" ones, in any
sufficiently complex FPGA project.

The use of Gnuradio will not affect the FPGA design at all. If you supply
the errors you're seeing we might be able to help further.

Hello all,

I am trying to design an RFNoC block using Vivado 2015.4, but I keep
running into synthesis and implementation critical warnings.

Can you explain to me step by step how to instantiate a working rfnoc
block WITHOUT using gnuradio? It seems that most information I am finding
online include the use of gnuradio.

I believe I have my environment setup correctly and I am calling the
noc_shell and axi_wrapper modules within my blocks. However, the errors I
am receiving are not stemming from the user code I have written, instead
the errors are coming from various design sources within the e310 fpga
source code.

Please help. Thank you
