# Regular Meeting (2020.5.4)

## Outline

* Testing UT4(sample code)
* HoughMappingGenerator code review(We discussed last week)

## 1. Test UT4

Testing environment:
![Test-HW](https://i.imgur.com/MI8UvEh.png)
Sample code include:

* Testing Artix-7 
    * Role: Configure(programing) Virtex-US by flash(ROM)
        * Data of Virtex-US isn't disappear when power off
    * So I have not test
        * In the first stage, we focus on the transceivers and implement 2D-trigger on the Virtex-US

* UT4-etc
    * Reset-button is working normally when I put it.
    
    * Power indicator has been lit when I provide power with our PS(max output: 5V 5A)
        * ![power indicator](https://i.imgur.com/DNH1v6o.png)
        * ![power on](https://i.imgur.com/mqOaWte.jpg)
    * Other functions, such as user LEDs, user switchs, I must separate main-board and sub-board, so I have not test those ones
        * If necessary, I will test in the future

* Testing iBert for UT4 Transceivers

    * Weird phenomenon after configuration:
        * 1. PLLs are *not locked*

        * 2. Power  seems not enough

    * ~~I guess that power supply is not enough when I using transceiver~~
    
    * Solutions:
        * Testing UT4 with VME Chassis
            * must setup remote programming server, it's inconvenient
        * Vivado seems can evaluate power dissipation after compilation
            * ![pow](https://i.imgur.com/SD7kgtk.png)
            * ~~First I to do (I'll report to you afteroon)~~
        * [5V-60A power supply](https://shopee.tw/LRS-350-5-%E8%96%84%E5%9E%8B-%E6%98%8E%E7%B7%AF-MW-%E9%9B%BB%E6%BA%90%E4%BE%9B%E6%87%89%E5%99%A8-5V-60A-~NDHouse~-i.8559906.49860617?fbclid=IwAR0883rtC3TIs7mZdKPYQKkz8gJASOI1aqxnbPM5R4OZtW7hmXROfJ7vHp4) co$t~700NT
