pb_type missing circuit binding

[buddynohair]

Hi,

this time i wrote a new custom block called "blackbox", which includes an adder and a flipflop module in the vpr-arch, and want to link it with the circuit model in the openfppa-arch. Unfortunately it shows me an error called "pb_type missing circuit binding". I checked pb_type annotation part with the tutorial and the examples you have given, but didn't find any problems. Can you please give me some advice?

Hello, I checked your architecture file. It is due to your binding lines <pb_type name="blackbox.[adder].ble.adder"> The name follows the naming in vpr on the pb_type name in full hierarchy. The format is as follows. <pb_type_name>[<mode_name>].<sub_pb_type_name>[<mode_name>] Therefore, the dot between blackbox and [adder] should not be there. I believe that is the issue.

Hi， i delete the dot between blackbox and [adder] , but the issue still exists

Hello, After checking your openfpga architecture XML, I see another problem. You define the pb_type-to-circuit_model binding inside the <pb_type name="blackbox">, which will be discarded by the parser. As you can see in the examples, the binding should be defined under the <pb_type_annotation> without any intermediate hierarchy. Also, I think the debugging information may be too brief to help. Therefore I created a pull request where the full hierarchy path of a pb_type will be printed out when the binding errors out.

Hello, im still confused with the pb_type_annotation format. I simplify the block blackbox, now only with one adder module. I also change the binding line in the openfpga-arc as followings

But it still shows me the error pb_type "adder" missing circuit model binding.

Hello, What you show here is not consistent with your XML file: <pb_type name="blackbox[adder].ble.adder" circuit_model_name="adder"/> When I change to this line to what you showed, OpenFPGA works.

Hello, thank you very much. I forgot to save the file before i ran the commend.
