Hi all, I m implementing a AHB master & slave integrated with Leon. I m facing the following problems In simulation I couldnt figure out how to use a self test...
Jiri, Could you confirm that the IO width can be configured to 32 bit even if the SRAM bank width is 16 bit ? It means there will be only ONE access to IO area...

Dear Jiri. I downloaded leon2-1.0.26-xst, and synthesized with design_compiler. I used leon.dcsh, script for design_compiler. After synthesis, I found some...
Run 'make xconfig' to configure the processor. Do NOT analyze debug.vhd, it is only for simulation. Unused ports should be removed by synopsys - which version...
The I/O bus width is independent of the prom and ram bus width. I/O area operations should not cause multiple accesses on 8- or 16-bit I/O buses, this is...
Hi all, I m facing a problem in writing to AHB slave via Leon . The read is working properly It dsnt give any error on write . But neither writes the value in...
Hi Ajay, I tried a simple AHB slave with couple of registers. I was able to write to the first register but nt to the second register. At the time of this ...
Hi karthik, In my case the write is proper from multiple registers.The problem is that it dsnt read at all . Though id does go in the write loop( i managed to...
Hi Ajay, Well my project was a uni one, which had dead lines. I talked to my supervisor about it and he said its fine. SO I didn't have time to look into it. ...
Hello,Jiri I want to implement a user peripherals on leon2, this device contains only 4 registers,since this device is slow, I am going to place it on APB. I...
Hi Jiri, I have just started with the new Leon3. It is full of greast features, wow!! I would like to use 3 UARTs and 2 Ethernet instances. How can I configure...
Read the grlib manual that explains how the plug&play concept works and how you add and configure cores. You can add any number of the same core, just make...
Hi Jiri, I have just started with the GRLIB. I would like use the PCI interface. I don’t understand the functionality of the input pin pci_66. Can you...
Jiri, Thanks for your answer. I've found some explanation. I confirm I/O bus width is independent of the prom and ram bus width. I tested the FIFO peripheral...

This pin is not used, the GRPCI core is intended for 33 MHz systems. Jiri....
Dear. I always thank you for your kind reply. My design_compiler version is V-2004.06-SP2 for linux. You said to remove unused pins, but I need these pins I...
Hi all, I'm trying to evaluate leon3 via grlib on an altera stratix. - i wrote a very simple program and generate a boot rom (nocomp option) - i wrote a nice...
hi David I use Stratix (1S25-5) and QuartusII (only) with good success at 80MHz (86MHz given by Quartus) you need to have the latest QuartusII version 4.2 SP1...
Hello! I am using leon2-1.0.10 processor for my SoC.When I synthesize this, with required ram black boxes using "leon.dcsh", I am getting few warnings but it...
Hello there. I'm trying to compile some C programs to execute through ModelSim with LEON2 model. The code consists of several C files. I have modified the...

For standard C programs, do not use the compile procedure for the leon test bench. Instead, use: sparc-elf-gcc -msoft-float -O2 app.c -o app.exe ...
Thank you for the help. The simulation ends with the processor in error mode. Is that expected? The reason I tried to run the program through the leon test...

The processor can only be stopped by putting it in error mode, that is also what the application does (implicitely) at the end. If you want to stop with ...
Hello, I'm facing a strange problem with the Leon2 mapped onto a Xilinx Microblaze board: As soons as I switch the Leon in debug mode (using the appropriate ...
The read-out from grmon is bad - wrong window numbers and impossible cache config (4 bytes/line). Start grmon with -i to see if the situations improves. Also,...
Hi, Thank's for your fast reply. I'm using quartus V4.1 SP2 But, I think I found something. I tried to embed the all system inside the stratix. Including the ...
Hello, By changing the baud rate of grmon, I could successfully download the hello.elf on to multimedia board. (I had to set the baud rate to 9600) Is it not...
