multiple level mif array cause error

[jinjie320621]

I design 3 modules: TestA, TestB, and TestC.
Test B and TestC are mif.

3 level hierarchy architecture: TestA is the top module, TestB is TestA’s child module, TestC is TestB’s child module.
TestB is instantiated as a mif array in TestA, TestC is instantiated as a mif array in TestB.

It will cause ICSC tool error: ScTool internal fatal error : No record in getBaseClass()

But when not instantiate TestC (or TestC is not a mif array), it means not have multiple level mif array, it will be correct.

Is it a bug of ICSC tool? How can I avoid it? Thanks very much.

Hello,

Thank you for this issue.

Currently inner MIF (MIF inside MIF) is not supported. You can use normal child module (not MIF) without limitations.

Would also recommend to use sc_vector for SystemC modules, signals, ports instead of C++ array.

Will update this issue when/if inner MIF supported.

That has been supported for sc_vector in Version 1.4.25.
See tests
https://github.com/intel/systemc-compiler/blob/main/tests/mif/test_sc_vector_mif5.cpp and
https://github.com/intel/systemc-compiler/blob/main/tests/mif/test_sc_vector_mif6.cpp

Please consider C++ array of MIF will not be supported.
