In a quite a rare circumstances, there is a need for a manual interconnect resource choosing. For example, in case of oversampling scheme (the situation where a signal feeds multiple registers, clocked by different phases of the same clock). In that case we need precise values of both data path and clock path, and usually we need to rule Quartus interconnect resource usage, not only placement.
For example, for a manual placement, we have an opportunity to choose elements and assign their place coordinates using "Location" assignment:
Are there any right way to do that (or something like that) for interconnect elements?
Thanks in advance.
Thank you very much for your answer.
I know about fractal synthesis and it is not what I mean I suppose.
Maybe my screenshot is misleading, it can be not just MLAB but any element as a value of "Location" Assignment - LAB combinational cell or delay chain or so on.
The answer that you gave is not about routing elements selection, it is about math blocks packing for area at the previous step of compilation - at Synthesis.
So my question is how to choose manually routing resources. As an example I added another screenshot from TimeQuest GUI -
Here I highlighted Routing Element type in timing path.
