Re: QSYS Subsystem Export Port order
I know this works for individual components, but try selecting the added subsystem and then go to the Component Instantiation tab. Can you click and drag the interfaces on the Signals and Interfaces tab? If not there, try opening the subsystem .qsys and then looking at the Interface Requirements tab. The left side of that tab shows the interfaces of the current system and I forget if you can drag and reorder them there.3Views0likes0CommentsRe: The best way to implement SignalTapII
How often do you need to switch a trigger condition column type between Boolean AND and OR? I can't say I've ever needed to do that more than once. Easy workaround though: add an additional trigger condition column. Set one column to Boolean AND and the other to Boolean OR. You have to do one more compile to set it up, but then, whichever one you want to use (or not use), enable or disable the checkbox at the top of the column. Enabling/disabling a trigger condition column is a runtime change that does not require recompilation or reprogramming of the device. Disabling a column skips over that column. And as mentioned previously, changing value cells within a column is also a valid runtime change that doesn't require recompilation. Another tip: if you want to avoid accidentally making a change that requires recompilation, set the locking option at the top of the Node list (I forget what it's called but there's a pop-up list there). This grays out any settings that would require a recompile.5Views1like5CommentsRe: State machine question in Arria X device
Not sure what you mean by "4W_HEADER1(33 clk)" vs. "4W_HEADER1(1 clk)". I see a state "4W_HEADER1" but that's it. Other than that, I'd try using parameter instead of localparam. I don't know if that affects the way Quartus "detects" state machines, but it's worth a try. You should also break up those super deep else/if statements. Pull that logic out of the main next state logic and use case statements and intermediate signal(s) instead in separate processes. Are you having timing issues?25Views0likes0Comments
