WebEdit 2: I got home and I realized I omitted another possibility, that deals with hierarchical schematics. The symbols and the schematics can only share one name, case insensitive, so, if you need two symbols pointing to the same schematic (avoiding duplicates of the schematic but keeping more than one symbol), you can simply make the second symbol … WebMay 13, 2014 · Change that type according to your needs). Save the symbol with a new name in LTSPICE's symbol library: save as -> LTSPICE_home\libsym\SIOV\S20K275.asy (you will have to create the subdirectory \SIOV the first time you create a SIOV varistor). The easy way: From within LTSPICE open the netlist (.asc or .mod file) of the subcircuit. ilthir

WebDec 14, 2024 · This is because the original symbol was designed to be a Q of type N and that won't access the .subckt mechanism. So you do have to change the symbol's attributes so that LTspice knows that it is a sub-circuit symbol and not a BJT symbol, anymore. So here is the same circuit, from above, but now implemented with .subckt, instead: WebAug 31, 2024 · To place an IC=0 directive in the symbol, point to the symbol, when the cursor changes to a pointing hand ctl+rht-clk the symbol. This should open the attribute field window for the symbol. Type IC=0 in the Value2 or Spiceline fields, then click ok. There is a"visibity" field at the right end that will make the value visible if checked.
