Anybody here with experiences with syntetising some 8051 core with JTAG debugger in FPGA ? What core can you recommend ?

What core can you recommend ?there is no standard JTAG debug for 8051 core, quickcores had some 8051 ipcore and jtag debug interface but quickcores is dead, so you cant obtain that source any more I bet any other available 8051 does not include jtag debugger and even it would there is no debug software that supports that so you would end up writing the debugger and jtag unit yourself anyway easiest is to take some 8051 core and just connect chipscope ILA's onto the bussses, that sufficent for many cases Antti

quickcores has become SiliconLaude -- www.siliconlaude.com -- and interesting 8051 cores with real-time JTAG debug are available.

Instead they offer radiation-hardened silicon... I am looking for an IP core to be put into a generic FPGA device.

The radiation-hardened devices are implementations of the quickcores IP in radiation-hardeneded FPGAs, the only signficant changes being that the external memory interfaces have been modified to operate with radiation-hardened magnetic RAM. I have found them to be helpful in my interactions with them in the past.

Quickcore had some nice examples, and seemed to offer a Multi-core 80C51, into generic FPGAs, and working on Std EVAL boards. Does anyone know what's happened to that side of their operation ? -jg

Have a look at the oregano 8051 design, http://www.oregano.at/ip/ip01.htm For the generic JTAG debugger look at Temento's Dialite product (http://www.temento.com/solutions/fpga.php), they provide vendor independent JTAG debuggers (they instrument at the RTL level).
