New Features in SimOne
User Feedback
The feedback with a message to the developers can now be sent from inside SimOne. With the Help→Feedback menu entry “Contact developer” window is opened.
At the window there are optional fields for the sender email, name and the message subject. The message text cannot be left blanc. If the message type is Question, the email to send the response must be provided too.
The message types are:
 Question,
 Suggestion,
 Bug,
 Interface issue or
 Other.
Additional information can be send:
 Scheme (or netlist),
 Current SimOne view screenshot (without Contact developer window),
 System information,
 Any other file.
The sent messages are stored in the history. To view them click the Message history button.
Touchstone model and Nport devices
SimOne now supports Nport components, specified with S, Z and Yparameters.
The parameters can be set either as expressions or as Touchstone files.
Nports can be placed to the schematic either
 as a primitive (toolbar icons ) or
 a component from included libraries of Touchstonemodels:
A new property is introduced for Laplace sources and Nports: MaxF. It defines the Inverse Fourier Transform step applied to the specified element (or model) in simulations. Note: this doesn't define the element itself, but only the behaviour of computational algorithms.
Graphs
Graphs in AC analysis can be displayed on the Smith chart.

Mathematical expressions
The following measurements can now be used as expressions:
Bandwidth  Bandwidth(expr, [level])  Bandwidth of the expr at the level of dB. expr By default level = 3 dB. 
СenterFrequency  СenterFrequency(expr, [level]) – the center frequency of the bandpass at the level of dB. By default level = 3 dB. 
Cutoff_Highpass  Cutoff_Highpass (expr, [level]) – the upper bound of the bandpass at the level of dB. By default level = 3 dB. 
Cutoff_Lowpass  Cutoff_Lowpass (expr, [level]) – the lower bound of the bandpass at the level of dB. By default level = 3 dB. 
DeltaX  DeltaX(expr, y1, y2, [cross]) – the distance on the X axis between the point with Y coordinate and the point with Y coordinate , occurring for the th time. By default cross = 1. 
DeltaY  DeltaY(expr, x1, x2 ) – the distance on the Y axis between the point with X coordinate and the point with X coordinate . 
FallTime  FallTime(expr, y1, y2, [fall]) – the distance on the X axis between the point with Y coordinate and the point with Y coordinate on the th fall of the graph. By default cfall = 1. 
firstY  firstY(expr) – returns the value of expr at the first point of the graph. 
Frequency  Frequency(expr, y, [cross]) – returns the frequency of the expr measured by level y. Cross is the number of value y. By default cross = 1. 
Inflection  Inflection(expr, [cross]) – returns the X coordinate of the point where the th inflection of the graph occurs. By default cross = 1. 
lastY  lastY(expr) – returns the value of expr at the last point of the graph. 
MaxY  MaxY(expr) – returns the maximum value of the expr. 
MaxX  MaxX(expr) – returns the X coordinate of the maximum value of the expr. 
MinY  MinY(expr) – returns the minimum value of the expr. 
MinX  MinX(expr) – returns the X coordinate of the minimum value of the expr. 
NX  NX(expr, [N=1]) – returns the X coordinate of the expr at the Nth point. 
NY  NY(expr, [N=1]) – returns the value of the expr at the Nth point. 
PeakX  PeakX(expr, [cross]) – returns the X coordinate of the function's peak point that occurs for the th time. By default cross = 1. 
PeakY  PeakY(expr, [cross]) – returns the value of the function at the th peak. By default cross = 1. 
Period  Period(expr, y, [cross]) – returns the frequency of the expr measured by level y. Cross is the number of value y. By default cross = 1.

RiseTime  RiseTime(expr, y1, y2, [rise]) – the distance on the X axis between the point with Y coordinate and the point with Y coordinate on the th rise. By default rise = 1. 
Slope  Slope(expr, x)  returns the tangent of the slope angle at . 
SlopeX  SlopeX(expr, slope, [cross]) – returns the X coordinate of the point at which the slope angle tangent equals , occurring for the th time. By default cross = 1. 
ValleyX  ValleyX(expr, [cross])  returns the X coordinate of the th valley of the expr. By default cross = 1.
