I have a stupid question, because my LEON runs with simple programms, but does not run with more complex programs. Has anyone success with the LEON on a...
Hi Jiri, I'm an undergrad electrical engineer, I plan on doing my senior design project on Leon, and I'd like to know the names of the people I should give...
Hello, We're putting Leon into an ASIC. I've got a little problem with my Register-file Dualport Rams: They are a little bit slow. The dual port rams are on...
Here are the patches we used with the Xess board. Included is also the VHDL for the configuration CPLD, you'll need to upgrade it's code first. uClinux...
I for one would be interested in the patches necessary to make Leon run on the XESS board. I was planning on spending next week to bring Leon up on an Xess...
... .. ... There are a number of things you need to do in order to get LEON running on the Xess XSV board. I'll send some patches, but I'm hoping to take the...
Hello, I got LEON work on a Xess XSV300 board (Xilinx XCV300 FPGA). I can boot form the Flash with a modification of Jiris pmon.c. (without including standard...
Hi, Is there any way to simulate the Leon processor using a synopsys-VSS (1999.10) ? If not, then can anyone recommend any other method of simulating the...
Hello, we think about using LEON for an internal project concerning object-oriented SoC-design. As I understood from the archive and the LEON homepage the core...

Since there are more and more people getting up to speed, I have released a simple boot-monitor that can download and start applications. It is small enough (...
Hi ! My target board has Xilinx XCV-300E. I heard that it is convenient to synthesis LEON with Synplify. So, I tried getting License for trial version. But I...
I wrote a ROM core generator (as I explained in the mailing list a few days ago). It should help to solve some common problems with instantiating ROM cores. It...
Hi all, Excuse me for this stupid question, but i wonder if Leon or a degraded version of Leon could fit into a Xilinx XCV100-4 FPGA ? I ask this because i saw...
