TGA Verifications - Overview : TGA Verification design consist of 5 main parts : TGA Verification design consist of 5 main parts :  PPC EMULATION  RocketIO EMULATION  Generator Checker  Reference Model of the Analyzer  Compare & Analyze Unit

PPC EMU GENERATOR TGA Verification – Block Diagram Script File ANALYZER GENERATOR CHECKER Reference Model of the Analyzer Compare & Analyze Unit Log out File Config File PPC EMU Packet Generator For the Analyzer

Project Description : The PPC EMU configure the Generator according to script files instructions. The PPC EMU configure the Generator according to script files instructions. The Generator Checker survey the outputs of the GENERATOR and verify that the results are appropriate to the instructions. The Generator Checker survey the outputs of the GENERATOR and verify that the results are appropriate to the instructions. A config file will configure the RocketIO EMULATION to generate different packets with different errors plants on it. A config file will configure the RocketIO EMULATION to generate different packets with different errors plants on it. The Compare and Analyze Unit analyze the Generator Checker results, compare the results from the real Analyzer with the Reference Model and analyze it. After that perform the analyzing results to log out file. The Compare and Analyze Unit analyze the Generator Checker results, compare the results from the real Analyzer with the Reference Model and analyze it. After that perform the analyzing results to log out file.

TGA Verification Features & Performance: Generator verification: Generator verification:  Number of packets  Packet length  Header length  Stamp length  Burst size  Inter Burst Gap  Inter Packet Gap  Header Data  Stamp Data  Start/End Padding Data

TGA Verification Features & Performance(Cont.): Analyzer verification: Analyzer verification:  Number of damaged/undamaged received packets  Loss of synchronization  Max/min transmission delay  Errors indication – CRC, disparity, ”not in table”, ”invalid K character”  Store damaged packets

TGA Features & Performance (Cont.): PPC EMULATION component PPC EMULATION component  Set the packet Header and Stamp  Configuration of the generator  Read the data from the Analyzer and pass it to the Compare & Analyze Unit RocketIO EMULATION RocketIO EMULATION  Configuration of the Packet Generator of the Analyzer  Plant errors in the data to the Analyzer in purpose to verify Analyzer function

TGA Features & Performance (Cont.): Compare & Analyze Unit Compare & Analyze Unit  Compare results between the real Analyzer with the Reference Model of the Analyzer  Compare between the Generator Checker results with the configurable parameters by the PPC EMU(from the script file)  Analyze the results and report to a log out file  The log out file includes simple messages that direct the user to the bugs
