If you can post your source and dsn file we'll have a look. Typically this happens when you externally wire a crystal etc. - this introduces an extremely high speed oscillator which bottlenecks the simulation and is completely superfluous anyway. Clock frequency is specified as a property of the microcontroller device.
11 de fev. de 2006 · 2,986. Re: speeding ADS. Just go to the task manager and in processes tab pick proper and give to it max priority, also do not tale a lot of points to run. But of course you can do it with other 3D simulators and for sure they will be more faster (like HFSS, CST etc.) David. radha. R.
20 de jul. de 2012 · You always need the 2 metrics (Test Coverage for SA and TC for Transition faults). TF patterns detect slow-to-rise and slow-to-fall faults while SA pattern detect stuck and open faults. @speed fault testting require 1 launch and 1 captur cyclee to be tested. For @stuckat, 1 capture cycle is often sufficient to detect a fault (unless there are ...
3 de nov. de 2018 · Assuming typical speed in FR4 is 15 cm / ns (0.015 cm / ps), I am trying to calculate the time to travel 400 mil (1.016 cm). I am not sure if the following calculation is correct. Speed = Distance x Time. Time = Speed / Distance. Time = 0.015 / 1.016 = 0.0148 ps.
1 de fev. de 2011 · I see that a lot of MCU input are not fast enough to capture such a high speed pulse, even some 24bit asynchronous counter, the parallel output is only the last 8bit, means the lower 16 bit information is missing. I wonder, normally how this high speed pulse train is counted with high resolution(at least 18 bit resolution).
31 de jan. de 2024 · I won't give the exact speed because it is a function of the load capacity and even though I have a 16-bit LRC it may not be easy to measure accurately. Let me put it this way, if I compare the slope of the rising edge of the STM32F3 and the output of the 74HC04 at 3.3V, they are similar, with a 5.5V supply (74HC), the slope of the 74 is already a bit steeper.Compared purely optically on the ...
1 de ago. de 2007 · 9,926. clockspeed. #define F_CPU is for defining clock speed of the processor. While your micro is running at 1MHz and you are defining 16MHz make the programme run 16times slower. Nandhu. N. Nahian. Points: 2. Helpful Answer Positive Rating.
8 de ago. de 2008 · This sounds as though you want to examine 5 seconds operation of a circuit running at 1 GHz. It's an example of mixing micro and macro events. It becomes mismatched and unwieldy in simulation. (It is not a problem with real electronics, of course.) Consider trying a longer timestep. Also try a slower switching rate in your simulated circuit.
20 de mar. de 2024 · 300,821. If "DC fan motor" is a usual electronically commutated brushless DC type, consider that it may be not suited for direct PWM operation. They usually involve a larger input filter capacitor, you'll need an external filter choke. Better use a fan motor with built-in speed control and separate pwm input that can be driven by logic level ...
24 de out. de 2021 · California, USA. Activity points. 35,626. Short answer is: you can't. The IO voltage of an FPGA is basically fixed. You'll need some external circuitry to switch your voltage levels. 0. Jun 1, 2022. #3.
