With synchronous FSM you have to be careful of time delay for the clock speed.....in asynchronous there is no clock there are no boundaries or restrictions

Navadeep•1/17/24, 7:37 AM

I suppose by synchronous youre referring to syncing with the clock signal. If so, it's all about the clock.

Do you want the event to happen at definite clock cycle intervals? - go woty synchronous
If the requirement is to have an external input form the user, an event occurrence in the process itself like or a flag or interrupt and control the state machine transition based on these, then you have asynchronous.

Navadeep•1/17/24, 7:44 AM

If time sensitive events, asynchronous can be faster as there is no need to wait for the next clock edge to come. It should be feasible to implement hybrid. I am curious now - will try it out. One way is to have synchronous FSM running along with async to override it. I am quite fuzzy about time delay and how to healthily override.

Navadeep•1/17/24, 7:45 AM

Something exactly like MCU running a task and interrupt getting raised and serviced.

I have very little experience so far and that too with interfacing memory controllers (RAM, Flash) with FPGA. So thinking in that context. I'd be happy to explore more from you on the hybrid approach

Hey @Petr Dvořák the other day in the Low-cost but still excellent oscilloscopes for SOHO thread you got on the topic of Smith charts.

Do you still use them in your hardware development efforts? Can you explain how you'd use a Smith chart to determine something like load input impedance?

Curious if @pallavaggarwal @Joseph Ogbonna @Aditya thakekar or others use these methods as well and when/where they apply them.

Ttechielew Hey @Petr Dvořák the other day in the https://discord.com/channels/1130679493799...

Joseph Ogbonna•1/17/24, 1:50 PM

my last design i did using Nordic nRF52840 which had a BLE on it. Wanted to use the smith chart, but found it a little bit difficult, but was recommended to use VNA device instead for my antenna tuning it get my desired value. So i dont actually use them in my design, but its helpful to a certain point.

Petr Dvořák•1/17/24, 2:20 PM

@techielew Well, the Smith chart is not a calculator. It is a special format of logmag chart in a round form. The Smith chart gives you information how the impedance varies with frequency. For the given frequency, the Smith chart can help you with finding a corrective matching network for your antenna feed point or transmitter output. The Smith chart can help us designing a matching network. It can help to design a matching network for all load impedance values because the Smith chart is designed for a normalized values. Our equipment use 50 Ohm or 75 Ohm. The Smith chart can be used to display the impedance characteristics measured by the given instrument and the given component, transmission line, impedance etc.

Aditya thakekar•1/17/24, 3:23 PM

Just for impedance characteristics it is used. Like data visualization techniques.

Apart from that I don't feel we need smith chart in designing.

Aditya thakekar•1/17/24, 3:37 PM

Basically, Smith chart is built by considering impedance, it can be used to analyze resistance and reactance parameters in both the series and parallel.
