## 1. Setting Environment
### Ubuntu on Virtualbox
- problem 1: add 250G disk on VM failed
solution:

- problem 2: internet doesn't work on VM
solution:

- problem 3: use ssh visit ubuntu on VM
solution:

### Install Xilinx Vitis

## 2. Multiplication
### Vitis HLS
#### step1: C simulation
#### step2: C synthesye
#### step3: Co-simulation
During co-simulation the block-level control signal is needed, so the pragma "ap_ctrl_none" must be commend (also in csim and csyn).

//#pragma HLS INTERFACE ap_ctrl_none port=return

#### step4: Export RTL
Before export RTL, remember to remove the comment and synthesis again.
