# Regular Meeting (2020.8.10)

1. Testing Fiber-loopback on UT4 with 10Gbps
2. Eye diagram (generated/Read by vivado, I also create a converter with python)
3. Discussing for computer
4. Problem for asking Sue-san
5. Synthesis 2D-code
6. New book regard tcl/advanve issue for vivado

## 1. Testing Fiber-loopback on UT4 with 10Gbps

* Same error as GTY (only 1 channel worked)

## 2. Eye diagram (generated by vivado)

* Generated chart files is *.csv* format, 
  seems can be plot by python-matplotlib

ch20 ~ ch23

## 3. Discussing for computer

* KEK

![](https://i.imgur.com/9uqkWY6.png)

* All of comsumer grade M.B. x570f can support to 128GB ram,

![image alt](https://i.imgur.com/npO03zK.png)

* and also price < 10,000NT


* I guess *one user on one compiter* maybe 64GB ram is enough

* This list I still selct 64GB ram

    ![](https://i.imgur.com/M5FTg3J.png)

    * 12 cores / 24 threads CPU
    * 32GB Ram \*2 (M.B. can up to 128GB max)
    * 850w Delta-plower platinum grade (effiency > 90%)
    * 1TB m2.nvme(pcie) SSD (Read: 3500MB/ Write: 3000MB)
    * if downgrade CPU to 8 cores / 24 threads
      * -> price -5,000NT

## 4. Problem for asking Sue-san

1. Request code(project) for test GTH/GTY with optical modules
2. 2D-Code and persistor (newest in CDC-firmware)
3. others?
    * ?

## 5. Synthesis 2D-code in vivado

* *persistor* only -> OK, 26m elapsed
  * Not sure these files are newest firmware in the CDC-firmware

* *my code 2D* 
  * has map only -> success
  * but can't casecade to *persistor* directly (Since data type)

* *source code 2D* 
  * lost some top files

* So I want 2D-Code and persistor (newest in CDC-firmware)

## 6. New book regard tcl/advanve issue for vivado
