15 févr. 2004 · 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.
17 oct. 2024 · In the circuit there is a signal coming from FAN which will be go into the circuit and the output of it goes to microcontroller. This signal tell weather the FAN is ON or OFF. basically this signal is used to check if the FAN is in working condition or not. I am just wondering can I give the PWM signal to the FAN to vary the speed of FAN.
20 juil. 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 nov. 2018 · Propagation speed is light speed/sqrt(Er,eff). Your assumed 0.15 m/ns (0.5 light speed) is roughly correct for embedded microstrip on FR4, microstrip has typically higher speed (Er,eff < 4), stripline lower speed (Er,eff > 4). You can use Saturn Toolkit, tab Conductor Impedance to calculate propagation speed for your actual transmission line geometry.
28 déc. 2011 · You need a high speed op amp with some current output capability (at least 100 mA). You also need to protect the varactor from inadvertent burn-out if forward biased. So there are two basic circuits: The single ended rail-to-rail op amp can not blow out the diode with a forward bias, so you can hook it up directly. The dual supply op amp needs ...
12 juin 2004 · hspice speed up simulation Besides fast options, autostop can help you as well. In addition, increase step for transient, AC,DC will help when too small is not necessary. Of course employing multi-cpu and use multi-thread job can make simulation fast dramatically.
2 mars 2010 · Location. Egypt. Activity points. 5,880. Re: Speed Grade in FPGA. Speed grade in FPGAs is used to describe the speed. A FPGA having a speed grade -5 is around 15% faster than a FPGA with speed grade -4. --. Amr Ali.
8 août 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.
18 janv. 2008 · Incremental synthesis and implementation is one way. If you don't change a lot of logic between consecutive runs it can significantly speed up the compile time. Note: Some run time improvements come at the expense of quality of results. This is not always the case, but turning off various optimizations will improve the run time of synthesis.
20 mars 2024 · 300,584. 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 ...
