PRBS Checker

• ON-CHIP SELF-TEST CIRCUIT BLOCKS FOR HIGH-SPEED APPLICATIONS
• MS Thesis by EKATERINA LASKIN of UNIVERSITY OF TORONTO
• https://www.eecg.utoronto.ca/~sorinv/theses/laskin_MASc_thesis.pdf
• Great illustrations and discussion.
• Provided two PRBS checkers.  
• The first version gave 3 error flags for each bit error if the errors are spaced further than the PRBS order.
• The second version promised to resolve this but my implementation found that consecutive errors were missed.
• Through Google Scholar, found 9 papers that cited this thesis.
• Zhang, Hongguang, and Deng Luo. "A low power 28 Gb/s 27-PRBS Generator and Check With Correlate Dual Outputs in 40 nm Technology." 2017 International Conference on Electronic Industry and Automation (EIA 2017). Atlantis Press, 2017.
• Has a diagram of a PRBS checker that is the same as the first version of Laskin thesis.
• Don't seem concerned about the 3 error flags for each error issue.  Not sure if they addressed this.
