1065271400_2323246 Apr 24, 2017 1:37 AM (in response to nishanta_46)hello,Nishant,
I am happy it worked ,thank you ,but I have more question ,I changed the FX3_AD9269_MT_USB3.cydsn ,16 bit data to 8 bit,and I also changed counter to 16367,but it shows "invalid state machine path for the simulation for state TH0_RD_LD" error,and I compile the state machine ,there is no error, when I view the timing it shows the message and there is no wave,why? By the way,when I configure the GPIF II slave,can I use the SPI?In other words,if SPI only work in the master mode of GPIF?thank you !
regards,
Alex

nishanta_46 May 3, 2017 2:42 AM (in response to 1065271400_2323246)The state machine timing does not let the state to move to "TH0_RD_LD" because the transition is based on DMA_RDY_TH0 getting asserted, which does not get asserted again by itself. You can check this by creating the scenario till state 7 (dont loop to the next state). This is because the designer doesn't see the DMA_RDY signals getting asserted again, but on real scenario it will (based on whether the host is asking the data). So, if you test on the hardware, you will see the state machine will move to "TH0_RD_LD" once the buffer of thread 0 becomes available again.
SPI can be used even when the GPIF is configured in slave mode.
