1. Testing Optical modules with ibert/UT4 (25Gbps )
2. Issue about OS for vivado
3. Def. file on HDL code for CDCTrig
4. Computer/Server for build project with Vivado/Vitis

## 1. Testing Optical modules (25Gbps)

* Pros.
* Cheap
* Cons.
* Filer could be damaged caused by design of plug

## 2. Issue about OS for vivad

[Refer here](http://xilinx.eetrend.com/blog/2020/100049001.html)

To reduce build time,

I recommand switch build environment from Windows to Linux.

Maybe we can raise(recommand) this issue in next CDCTrig conf.

## 3. ~~Def. file on HDL code for CDCTrig~~

~~Since I'd like to follow now def. of CDCTring to modify code.~~

**Found!**

## 4. Computer/Server for build project with Vivado/Vitis

### Solution 1: High performance for single user


* 12-cores-cpu
* 32GB normal RAM
* 1200W power supply (90% efficiency)

### Solution 2: High performance for multiple users

Note: commerical grade, but it's very high end commerical grade


* 24-cores-cpu
* 64GB ECC RAM
* 1200W power supply (90% efficiency)

### Solution 3: Server. Offical recommand

***Very expensive.***

#### Server 1:


* 8-cores-cpu* 2
* 64GB ecc RAM

#### Server 2:


* 16-cores-cpu* 1
* 64GB ecc RAM
