Hi,  
I took a trace from SPI lines and I want to find a specific sequence in the trace.  
I saw a way to find one byte but didn’t find an option to find few bytes togheter:

Can someone help me with that?

@nehadad This is actually one of the most requested features, and unfortunately, we haven’t implemented it yet. We’re keeping track of this in the idea post below. I added a vote and comment for you to track your need for this as well:

What kind of sequence do you generally look for? One potential workaround is to use the “SPI Transaction Framer” HLA extension to group together SPI transactions. Then you can search within that group. I’ve provided an example image below:

Great! thank you
