What schematic tool (VHDL) is the best?

Aug 13, 2004 5 Replies

The question is result of experience in designing Xilinx chip with Xilinx Foundation 2.1i (very old tool)and ISE6.2. The first have not good enough VHDL creating tool, the socond is newest but schematic editor has many...many bugs!!



Anybody has experience with other free GOOD schematic tools ?

You can use the free Quartus II Web Edition which has a good schematic editor for Altera parts. The Quartus II Web Edition can be downloaded from:

But I cannot use Xilinx chip as target - is any possible way to do it? Regard Buke

Xilinx

But you should refrain from using records in your port declarations if you use it, because the tool can NOT handle them. Subroto, is this something Altera considers to include in the next version of Quartus?

Manfred, I am unclear by what you mean by records in port declarations in a achematic editor. Can you elaborate?

Sorry for being imprecise. If you write a module in VHDL having records in its port declaration, Quartus does not allow to generate a symbol for it (which one might like to use in the schematics afterwards). I was told once, that this is due to limitations within the Quartus schematic editor.
