modelsim student edition difference

Hi,


Can anybody please let me know, What's the difference among Modelsim PE, SE, LE and XE tools.

To simulate VHDL/Verilog code for FPGAs, which software i have to download??


Regards,
Viswa

I don't think you want LE. It doesn't support VHDL.

Hi,


Thanks for the reply.

Modelsim PE Student version is available for free on web. Is this enough to simulate FPGAs for functional & timing verification?

modelsim pe se difference

That sounds like a good choice. The main thing you don't get is support.

That version may not support both VHDL and Verilog simultaneously in the same simulation. If that's important to you, investigate further.

No -- the Student version can't the vendor cell-libraries. (You need these for gate-level simulations, or if your RTL directly instantiates any vendor IP-blocks, like the DSP48, BlockRAM, transceiver, etc.)

The XE edition (free-one) comes with Xilinx's libraries precompiled. I'd start there.

And like someone else said, none of the free Modelsim editions (OEM or Mentor) allow mixed-language (VHDL+Verilog) simulation. I also noticed Systemverilog support has been disabled since last year. (Before that, you could compile and run limited Systemverilog simulations, if you limited yourself to 'Design' constructs only.)
