Can't find Pipeline channel definition

[DiamantisPa]

I saw in the documentation that a pipelined version of the channel is possible.

But i can't find the definition of the channel in the library and i get an error when i try to instantiate one.

Connections::Pipeline<Data_t> a;
incomplete type is not allowedC/C++(70)

Are pipelined channels not available in the opensource library?

That may be because the default value for the second template parameter is missing is Pipeline's definition (likely a bug). The code is located in nvhls_connections_buffered_ports.h, line 318. Could you try:

Connections::Pipeline<Data_t, AUTO_PORT> a;

and see if it works?

[npfet]

On closer inspection, Pipeline is first declared, with the default template parameter, in connections.h from Connections (line 260)

Thus, Pipeline should be working. There is also a unit test for Pipeline<>. You can try running make sim_pipeline in cmod/unittests/ConnectionsTop/ to see if it compiles cleanly. Also, double check that #include <nvhls_connections.h> is being included in your code.

Hope that helps,

Hey Nate,

Thank you very much for your feedback. I saw the unit test cmod/unittests/ConnectionsTop/ and understood how Pipeline channels work. Based on the documentation i thought they can be used similarly as the Combinational ones but it seem that their extra latency and capacity is just added to a Combinational channel.

Again thank you for your time. Cheers.

Cheers. Closing the issue.
