Honored ContributorWhat is the use/relevence of inst in .bdf files.
I'm just starting to use Quartus with Block Design Files -- very impressed. Coming from a KiCAD background it seems natural.
Two things have me puzzled: What is the relevance on "inst" in each block. As I add components the number seems to increase. Is it just a way of identifying a block for debugging etc. or is there more to it. Second, its unclear to me what the relevance/difference between "Analysis & Synthesis" and "Fitter (Place & Route)" are. Do I use both, one or none before doing a compile, none, once, or every time. Thanks in advance guys, hopefully questions like these will be helpful to other newbies. John2 Replies
Altera_ForumHi John,
--- Quote Start --- What is the relevance on "inst" in each block. As I add components the number seems to increase. Is it just a way of identifying a block for debugging etc. or is there more to it. --- Quote End --- Yes, It`s for identification purpose, it can be modified using “Symbol Properties”. --- Quote Start --- Second, its unclear to me what the relevance/difference between "Analysis & Synthesis" and "Fitter (Place & Route)" are. Do I use both, one or none before doing a compile, none, once, or every time. --- Quote End --- These are the Compilation steps, for creation of netlist you must do first "Analysis & Synthesis". Refer “Intel Quartus Prime Integrated Synthesis Design and Compilation Flow” & “Intel Quartus Prime Design Stages for Incremental Compilation” from handbook. https://www.altera.com/documentation/mwh1409960181641.html#mwh1409959376628 Let me know if this has helped resolve the issue you are facing or if you need any further assistance.
