We have not integrated the support of simultaneous multiple applications into Insider compiler. Instead, we provide a template that supports three concurrent applications; the user can replace the placeholder kernel with their application logic.
This version is simply a proof of concept. Since it is not integrated with Insider compiler, the user needs to manually add the reset logic into their kernels which is somehow cumbersome. For the normal use case, please adopt the single-application version which has the full end-to-end compilation support.
The same as the one in the single-application version.
We provide the template in the template folder which is structured as the following.
template
|------- cosim # The template for C-RTL co-simulation.
|------- host # Host code folder which contains the data generator and the host program.
|------- synthesis # The template for code synthesis.
synthesis folder contains the code for the end-to-end execution. It contains three very simple pass-through kernels (kernels/app_pt_{0, 1, 2}) that have different executing rates. The user can replace that with their application logic, and interconnects.cpp should be modified accordingly.
After that, execute staccel_syn to generate the project folder for the code synthesis. Steps go exactly the same as the ones in the single-application version.
Execute staccel_csim in the folder Insider-multiapp/template/synthesis/ will generate the C-Sim folder csim. After that, edit csim/src/interconnects.cpp to add user's CSIM logic. Steps go exactly the same as the ones in the single-application version.
We have already provided an example at Insider-multiapp/template/synthesis/csim. Please refer to it to see how to write the CSIM logic.
We provide a template at Insider-multiapp/template/cosim/. User first needs to replace kernels/app_pt* into their application kernels, and then updates interconnects.cpp accordingly to instantiate them. After that, execute staccel_syn to generate the project folder. User needs to modify project/software/verif_rtl/src/test_main.c to add their COSIM logic. The originaltest_main.c contains our example code.
Finally, execute make C_TEST=test_main in project/verif/scripts. Steps go exactly the same as the ones in the single-application version.
