Debug Support

Based on the R8051XC2 microcontroller core, the platform can be equipped with a complete debugging solution (EASE) which consists of:

• The On Chip Debug Support (OCDS) module built in the microcontroller core
• a USB-based Debug Pod for communication between the target IP core and the debugging software
• EDIk-51 software for interfacing with Keil μVision compiler/debugger

EASE helps SoC designers debug their applications by supporting:

• Standard debugging features (Code download, FLASH programming, Memory inspection, and Run/stop/step control)
• Optional debugging features including Program/Data Trace
• TCP/IP support for remote debugging

Options

• EDIF netlist for FPGA and low volume production
• Application-debugging Support Environment (EASE) that includes
• Debug hardware for R8051XC2 controller
• Software plug-in for Keil environment
• Dedicated USB pod for data exchange device between debug hardware and personal computer
• Evaluation system including:
• EB5-Tiny Development Board
• Implementation for Xilinx FPGA
• A PHY Extension board that meets the USB 2.0 Transceiver and Macrocell Tester (T&MT) Interface specification, and can be used to perform PHY interoperability testing for any USB transceiver
• R8051XC2 specific options:
• Pre-configured R8051XC2-A and -B versions
• Fully configurable version of R8051XC2 (R8051XC-F)

Support

The core as delivered is warranted against defects for ninety days from purchase. Thirty days of phone and email technical support are included, starting with the first interaction. Additional maintenance and support options are available.

Verification

All subcomponents were functionally verified with an HDL testbench using their individual test suites.

Deliverables

The core includes everything required for successful implementation:

• Verilog/VHDL source code or FPGA netlist
• Sophisticated Verilog 2001/VHDL Testbench
  
• Simulation script, vectors, expected results, and comparison utility
  
• Synthesis script (ASICs) or place and route script (FPGAs)
  
• Comprehensive user documentation, including detailed specifications and a system integration guide
  
• Complete C language source code set, example applications, documentation and integration guide for USBFS-51 Software Stack deliverables
