Developing the Manchester Receiver MATLAB Functions
Link for ModelSim verifies VHDL hardware in MATLAB as a function. You
must develop a MATLAB function for each model component you need to verify.
Given that the VHDL model for the Manchester receiver consists of three sections
of VHDL code, we need three corresponding MATLAB functions:
| I/Q convolver | Verifies that the VHDL I/Q convolver code computes expected output
for a randomly generated stream of samples. The MATLAB function verifies this
by computing the convolution for the inphase and quadrature waveforms (i_wf and q_wf).
The computation is implemented as an XOR and accumulation of the binary signals. |
| Decoder | Displays a plot of the I/Q mapping generated by the decoder for visual
verification. |
| State counter | Generates the inphase and quadrature waveforms. The MATLAB test bench
function has complete control of signals applied during the simulation, including
clock generation, resets, and so on. |
The following sections highlight areas of code in each of the three
MATLAB function files that are of interest for a ModelSim and MATLAB test
bench. The files are located in modelsimdemos.
