hi,
maybe someone can help me. I have a problem and i don't know what i'm doing wrong.
I have a waveform (only with 'normal' states) that is working fine. But i want to implement it with a flow state.
The waveform is used to read out data from an imager.
Some data:
- USB controler runs at 48 MHz
- GPIF runs at 48 MHz
- imager runs at 12 MHz
- LINE_VLD: line valid signal from the imager; while LINE_VLD=1 the imager puts valid data on the bus
Because the imager runs at 12 MHz the waveform contains 2 states and 2 decision points (so the GPIF will run at 48 MHz but read with 12 MHz).
This works fine for waveform 0 ('normal' states). But how can i do this with a flow state (waveform 2)?
I have uploaded the waveforms:
