To Run environment just do the follow command
58,4 → 133,20
bash run.sh
```
 
Whit this simulation you can generate till 1000 data. This a sample used to proof viability using icarus verilog like a simulator whit mixed code. More information enter in contact with some propose.
###What I have done till now
 
- Graphical interface to a better experience
- Dinamic change clock during environment execution
- A set of baud rates i found across internet to test suit
- A output file in html format TX SystemC 2 RX Verilog contain data compared
 
### BUGS ? :-(
 
- Crashes when you change frequency with no specific baud rate
- Log in html data goes wrong after a reset
 
### What i will do on future if i still alive :-D
 
- Make output file in html format TX Verilog 2 RX SystemC contain data compared
- Found the reason 'real one' to crash simulation on change clock
- Make avaiable to user insert data during execution
