Customs block API creation using TFL

Hi,

I have created API for all individual arithmatic block like ADD,SUB etc..

I like to know can we able to create the customs block like combination of ADD and SUB for 3 inputs for that i will write an respective API. Is it possible to do this in TFL

Please help!!!

Thanks and Regrads, Nithin

TFL is used to replace operators like +, -, etc. or basic math functions like sin, cos, etc. It appears that you need to build a custom block, for which, you can create a new Simulink block by writing an S-Function. You can provide a TLC file to call into your API - see Inlining S-functions to find out how the TLC file is used for generating code from the S-function.

Currently i'm using TLC only to generate the code for my Custom block. But problme is there are lots of constrain there are to take care of those block if i use this TFL i feel will be more better .

And also one more Constrain is i may not no how many be exits in my desing model, how to replace that also.. If I use it in TFL way, no need to consider about the usage of customs block in model.

Unfortunately, as I explained earlier, I don't think TFL will solve the issue of replacing functions other than the ones listed in the documentation. Perhaps you can talk a little more about the constraints you are facing with the S-function+TLC approach? Sorry, I don't understand your second comment about not knowing the number of exit points. Perhaps you can start a new question and specify examples to help us understand the issue better.
