Tool/software:
Greetings,
Spruii0e section 9.3.3, Figure 9-9 shows that the signals CLBx_OUTy are derived from OUTLUT0-OUTLUT7. But section 9.4.6, Figure 9-18 shows CLBx_OUTy as being the output of the AOC with the OUTLUTy being the input to the AOC. So I’m confused as to which is correct or if Figure 9-9 inadvertently omitted the AOC. Of course, this raises the question of what the source is for CLBx_OUTy in Table 17-5 Output X-BAR Mux Configuration Table etc.
What am I missing?
Thank you,
Ed
Hi Luke,
I have attached a diagram which I hope will illustrate my confusion. I used OUT4 because it and OUT5 go the most places.
The picture shows connections according to the figures or tables identified. It is obviously wrong because nothing is connected to the AOC, and the Peripheral Signal Mux is not connected to anything because it doesn’t know which CLBx_OUTn to connect to. So where is my thinking incorrect? My gut says that the source for Figure 9-9 should be the AOC.
Thank you,
Ed
Hi Ed,
This diagram from the TRM makes it clear that CLB_OUTn is a always the output of the AOC:
Let me know if this is still confusing or if you'd suggest an update to any of the TRM diagrams to make this more clear.
Thank you,
Luke
