Microchip Libero 2025: VHDL component library??

[nctnico]

I'm working on getting to grips with the Libero FPGA tools from Microchip. One thing I'm missing is a VHDL component library to instantiate FPGA primitives. The IDE can only create Verilog templates which are useless to me. I've tried to find some VHDL examples for Libero but so far I have failed to find anything. Any tips or hints on where to look are welcome.

Hi,

To an extent, they provide some templates in their "Macro Library Guides", see for example
https://ww1.microchip.com/downloads/aemdocuments/documents/fpga/core-docs/Libero/12_1_0/Tool/pf_mlg.pdf <-- PolarFire Fabric elements.

Best regards,

Thanks. I already found that document but I would like to avoid creating VHDL components for the primitives I need manually. Even though Libero is set the generate VHDL component templates, it generates Verilog. I've opened a case with Microchip. See what they come up with.

I got a reply from Microchip. The way to get some VHDL example code is to go through the schematic entry part and generate VHDL code from a schematic you can draw    That is also the way to get component declarations for primitives. Sigh.

I found a slightly better solution compared to using the schematic route. I dump the Verilog toplevels for the IP cores Libero created into Claude (AI) and let the AI create VHDL components declarations. Works like a charm!

It's nice the tool generates the VHDL code for you!
