Feb 15, 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.
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.
Dec 28, 2011 · 37,988. 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.
Nov 3, 2018 · The two last lines are completely wrong, time = distance/speed 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 >
Jul 20, 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 ...
Jan 31, 2024 · VolFM+ / Iio = RdsOn = 400mV / 20 mA = 20 Ohm but this is limited to 3.6V. If you want a buffer with a 5V swing, then most CMOS 5.5V logic is 50 Ohms +/- 33% or so. So you could use 3.3V output from a STM32 port into a 5.5V logic buffer and use 3 or more inverters in parallel to lower the RdsON.
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.
Feb 3, 2015 · For a maximum speed, I'm writing on sector. The problem is that the SPI doesn't reach the max speed allowed. In the data sheet the max speed is 25 Mbps, so about 3 MBps (the SD is a SDHC with a min speed of 10 MBps ). In mikroC, I set PBCLK=SYSCLK, and divider=8, where SPI_clock=PBCLK/divider.
Mar 14, 2006 · 1,298. Activity points. 7,491. Re: SPEED GRADE. The lower the -X the faster the FPGA. The speed is specified in terms of the tpd (pin-to-pin delay) parameter in the FPGA datasheet. This affects the maximum operating frequency of your design in that particular FPGA. Jun 26, 2006. #3.
Apr 19, 2006 · I'm developing Motor Speed Controller for Permanent Magnet Synchronous Motor(PMSM).I don't know why people love PWM so much for controlling the speed of the DC/AC motor.Every where I see is the PWM method for speed control, mostly in H-bridge manner equiped with transistors.I have my university final year project that is SCR based DC motor(1-phase) speed control in closed loop.So I'm desiging ...
