Honored ContributorHJS, thank you for your reply.
--- Quote Start --- if you can use the DSP AMI control signals directly as avalon master signals (even it is an asynchronous interface the signal are related to the a clock) you can use a simple tcl script to export the avalon master signals to the top level. --- Quote End --- I think this is the solution. But I'm not very expert with tcl scripts. Can you suggest me a reference or give me an example. --- Quote Start --- An others solution is to build your own dpram component with one avalon slave interface and one export interface. AFAIK simply exporting one port of the sopc builder dpram is not possible. --- Quote End --- Infact I tried this before asking here. At the moment I'm doing this: I created a lpm dual port ram block with Quartus megawizard; then I defined a new sopc component based on this dp ram, one port connected to Avalon signals and the other exported. No problem about the exported signals, since the interface is exactly the same as the current project, with external lpm dp ram block. But I'm concerned about the port connected to Avalon bus: I don't know if the direct connection between Avalon and lpm signals is correct. I attach the resulting tcl file generated by sopc builder component editor.
