TMS320F280025C: CLB Function

Part Number: TMS320F280025C
Other Parts Discussed in Thread: C2000WARE

Hi Experts,

When I using the CLB peripherals of tms320f280025C and study the example in C2000WARE.

For the project 1 (combined logic) of CLB, it is found that the logic information of the LUT in the syscfg file configuration (as shown in Figure 1 below) is not reflected in the code.

Is it in the function as shown in Figure 2? How to understand this function? Could you comment on this? Thanks.

Best Regards

    Hi Songzhen,

    You are correct, that function is configuring the LUT submodule with the equation created in the CLB Tool. The configured LUT function is encoded into a hex value, which you can see in the clb_config.h function

    We have designed this CLB tool to abstract away the actual bit manipulation that is used to configure the CLB since it is quite difficult to understand for CLB users.

    Regards,
