Can anybody help me to run full strip simualtion on my excalibur epxa4-1020(embeded arm 9 device) ? . i followed the instructions on altera manuals, but i still can't see correct disassembly log. Note that Altera support is not responding on excalibur related issues. Regards, Arie
Excalibur full strip simulation on solaris.

This manager was thinking about Excalibur until finding out it was not recommended for new designs, and that there wasn't a replacement. He had one question I couldn't answer: Why? ARM seems to be very popular. An ARM in an ram-based FPGA with enough gates to make the interfaces required would have made a nice product. Not worth rewriting a bunch of software to fit it into a V4 with a PPC. Why did Excalibur die? -- Phil Hays Phil-hays at comcast.moc (remove moc and add net) should work for email

Actel is promising soft-core ARM licensing for their PA3 family. But there is no PA3 silicon shipping as of today. the chinese nnARM softcore nnARM core, it does synthesise ok, but its very huge :(, well at least the register array is done badly as it alone occupies 50% of Virtex-4 LX25, I havent looked if the rest of the nnARM is useable if the register bank would be optimized Antti PS the nnARM source code should be easy to locate with google if anyone has interest in it.

But large companies are not interested in attracting sharks... I mean lawyers. Also the clock rate would need to be higher than I think that a softcore processor written as a student project is likely to achieve. -- Phil Hays Phil-hays at comcast.moc (remove moc and add net) should work for email

I know the device is not recomended for new designs, i use it for prototyping, final product will be based on ASIC with ARM core inside. i dont know of any other protoyping solution that can offer 200MHZ ARM9 processor + fpga. Arie

This is a requirement on my system since it has transfer address is managed by hardware. Thanks, Arie.
