This is the SandBox, a page anyone can edit to learn how to use the wiki.

Some codebox:

```python
from enum import Enum, unique
from nmigen import *

@unique
class selects(Enum):
    sel_A = 0
    sel_B = 1
    sel_C = 2
    sel_D = 3
    sel_E = 4
    sel_F = 20

class Top(Elaboratable):
    def __init__(self):
        self.in_ = Signal(selects)
        self.out = Signal()
    
    def elaborate(self, platform):
        m = Module()
        m.d.comb += self.out.eq(self.in_)

        with m.If(self.in_ == selects.sel_F):
            m.d.comb += self.out.eq(1)
        with m.Else():
            m.d.comb += self.out.eq(0)

        return m

from nmigen.back import verilog
f = open("top.v", "w")
top = Top()
ports = [top.in_, top.out]
f.write(verilog.convert(top, name='top',strip_internal_attrs=True,ports=ports))
```

# experiment with single bullet

heading

* hello
* bullet2
```
     test indentation
     test again
```
