Using oscillograph waveform file CSV as the Pspice simulation signal source

hi,

     I save the waveform file of the oscilloscope as CSV file format.

     Now, I need to use this waveform file as the source of the low-pass filter .

     I searched and read the PSPICE help documents, and did not find any  methods. 

     How to realize it?

     Are there any reference documents or examples?

     Thanks!

Crystal Oscillators

Hello, Currently i am designing a 96MHZ crystal oscillator using pierce topology and also I use for amplitude gain control circuit for regulation. The problem is when i run a PSS + Pnoise i get these warnings :

WARNING (CMI-2375): M2: Vgs has exceeded the oxide breakdown voltage of `vbox' = 6 V.
WARNING (CMI-2375): M4: Vgs has exceeded the oxide breakdown voltage of `vbox' = 6 V.
WARNING (CMI-2377): M4: Vgd has exceeded the oxide breakdown voltage of `vbox' = 6 V.
WARNING (CMI-2377): M3: Vgd has exceeded the oxide breakdown voltage of `vbox' = 6.6 V.

and also WARNING (CMI-2682): M5: The bulk-drain junction forward bias voltage (1.38154 V) exceeds VjdmFwd'=851.514mV ,The results are now incorrect because the junction current model has been linearized

Note : i am using Supply 1.2 V hence it is not possible to exceed the oxide breakdown. 

So i am asking why i am getting these warnings , it could be a convergence problem and the Results computed are not corrected.

Also when running DC and transient , i don't get these warnings.

PSS Shooting - High Q crystal oscillator - Simulator by mistake detects a frequency divider

Hi *,

 

I am simulating a 32kHz high Q crystal oscillator with a pulse shaping circuit. I set up a PSS analysis using the Shooting Newton engine. I set a beat frequency of 32k and used the crystal output and ground as reference nodes. After the initial transient the amplitude growth was already pretty much settled such that the shooting iterations could continue the job.

 

My problem is: In 5...10% of my PVT runs the simulator detects a frequency divider in the initial transient simulation. The output log says:

 

Frequency divided by 3 at node <xxx>

The Estimated oscillating frequency from Tstab Tran is = 11.0193 kHz .

 

However, the mentioned node is only part of the control logic and is always constant (but it has some ripples and glitches which are all less than 30uV). These glitches spoil my fundamental frequency (11kHz instead of 32kHz). Sometimes the simulator detects a frequency division by 2 or 3 and the mentioned node <xxx> is different depending on PVT - but the node is always a genuine high or low signal inside my control logic.

 

How can I tell the simulator that there is no frequency divider and it should only observe the given node pair in the PSS analysis setup to estimate the fundamental frequency? I have tried the following workarounds but none of them worked reliably:

 

- extended/reduced the initial transient simulation time

- decreased accuracy

- preset override with Euler integration method for the initial transient to damp glitches

- tried different initial conditions

- specified various oscillator nodes in the analysis setup form

By the way, I am using Spectre X (version 21.1.0.389.ISR8) with CX accuracy.

 

Thanks for your support and best regards

Stephan

The First Disciple

"Cain brought an offering to the Lord of the fruit of the ground. And Abel . . . brought of the firstlings of his flock and of their fat portions. And the Lord had regard for Abel and for his offering; but for Cain and for his offering He had no regard" (Gen. 4:3-5).

True discipleship is characterized by obedience to God’s Word.

In John 8:31 Jesus issued an important statement to a group of people who were showing an interest in Him: "If you abide in My word, then you are truly disciples of Mine." Sadly, they rejected His words, proving themselves to be less than true disciples. Jesus went on to explain why: "He who is of God hears the words of God; for this reason you do not hear them, because you are not of God" (v. 47). They listened but didn't really hear. They were interested but not truly committed. They were hearers of the Word but not doers (James 1:22).

In contrast, Abel did what God told him to do. He was, in effect, the first disciple. He was probably a better person than Cain—more friendly, moral, and dependable—but that's not why God accepted his sacrifice and rejected Cain's. Abel trusted God, and his faith was counted as righteousness. Like Abraham, whose faith was evidenced by his willingness to obey God and sacrifice his son Isaac (James 2:21-22), Abel's faith was evidenced in his obedient offering. He didn't rely on his own goodness but acknowledged his sin and made the prescribed sacrifice.

Perhaps God indicated His acceptance of Abel's sacrifice by consuming it with fire, as He did on other occasions in Scripture (Judg. 6:21; 1 Kings 18:38). But whatever means He used, God made his pleasure known to Abel.

Abel's brief life conveys a simple three-point message: we must come to God by faith; we must receive and obey God's Word; and sin brings serious consequences. If you hear and heed that message, you'll walk the path of true discipleship and be assured of God's pleasure.

Suggestions for Prayer

Make it your goal to please the Lord in everything you do today. Seek His wisdom and grace to do so faithfully.

For Further Study

Read these verses, noting what they say about pleasing God: 2 Corinthians 5:9; Ephesians 5:6-10; Philippians 2:12-13; Hebrews 11:6; and Hebrews 13:15-16, 20-21.
