What is spice subcircuit?
A subcircuit definition contains Spice circuit elements, has a name and specifies the circuit nodes that connect it to the main circuit. Creating a subcircuit allows you to reuse the circuit multiple times in a design and in future designs. Subcircuits are similar to subroutines in software programming.
What is a netlist in SPICE?
A circuit description in spice , which is frequently called a netlist, consists of a statement defining each circuit element. Connections are described by naming nodes. (The usual names are actually numbers.) One node name has a defined meaning.
What is probe in PSpice?
The PROBE statement included in the PSPICE Netlist generates a file, PROBE. DAT, for viewing the analysis on the computer monitor. If the PROBE program is executed, an output can be obtained as shown in the figure.
Where do I find the subcircuit file in 5spice?
Find the file (Xfer1.cir or Xfer2.cir) in 5Spice/WinSpice and find the indicated line number in the file. The subcircuit lines you see are copied from the subcircuit file, sometimes with the syntax translated. Now open the subcircuit file, find the matching line there and fix the error in the subcircuit file.
How does a subcircuit connect to a subname in spice?
The number of nodes on the call line must match the number listed in the .subckt line of SubName. Spice connects the nodes from the call line to the subcircuit in the order they are listed. Note: In 5Spice, if one subcircuit calls another subcircuit, both subcircuits must be in the same file.
Where are spice control lines stored in 5spice?
Spice program control lines may not appear within a subcircuit definition. In 5Spice, subcircuits are stored in the program’s library. You may add any subcircuit to the library and link it to the schematic’s subcircuit symbol.
How to create a subcircuit In LTspice 3?
Creating Subcircuits and Hierarchical Blocks in LTspice 3) Open the Symbol Attribute Editor to enter the appropriate information. a) Select Edit ÆAttributes Æ Edit Attributes. i) Select Cell in the Symbol Type drop-down box. ii) Select Prefix, type X in the Prefix = box.
