A single bit of VHDL bit type is represented in C/C++ as a single byte. The following table shows the values of bit and their C/C++ equivalents.
bit Value |
C/C++ Byte Value (Decimal) |
|---|---|
'0‘
|
0 |
‘1‘
|
1 |
Example code:
// Put a '1' on signal "clk," where "clk" is defined as
// signal clk : bit;
const char one_val = 1; // C encoding for bit '1'...
int clk = loader.get_port_number("clk");
loader.put_value(clk, &one_val); // set clk to 1
