Description

This is a configurable Atmel processor and support eight configurations:
1) REDUCED
2) MINIMAL
3) CLASSIC_8K
4) CLASSIC_128K
5) ENHANCED_8K
6) ENHANCED_128K
7) ENHANCED_4M (Not supported yet)
8) XMEGA

I provide the links directly to GIT projects for easy update.

The processor IP and several IO IP's and can be downloaded from here: https://git.morgothdisk.com/VERILOG/VERILOG-UTIL-IP/tree/masterxmega_core

The implementation example will oscillate between DIGILENT Arty and NexusVideo depending where I am when I make the last update and can be downloaded from here: https://git.morgothdisk.com/VERILOGVERILOG-XMEGA-CORE-IP-TST

On this directory, under the AtmelStudio project example debug directory's is an application that help developers to easy convert .hex files to .mem files and is described here: https://git.morgothdisk.com/VERILOGINTEL-HEX-TO-VERILOG-MEM

The implementation for LATTICE MachXOFL Starter Kit can be downloaded from here: https://git.morgothdisk.com/VERILOGVERILOG-XMEGA-CORE-IP-TST-LATTICE

On LATTICE platforms it seems that Latice Diamond have some issues with generic distributed BRAM RAM's and ROM's, until Lattice will give a workaround for this issue without using IPxpress.

All details about this core on GIT

I begin to add support for this core on CPP-SDK that can be found here: https://git.morgothdisk.com/C-CPP/MULTIPLATFORM-CPP-SDK/tree/masterExampleXmega_FPGA
