Figure 1-4 shows the Cadence Library Structure where:
■ Each individual library is stored in a directory bearing its name.
For example, the Cadence's standard DIODE library resides in
the directory /share/library/diode/.
■ Under each library, there are one or more cells, each residing in
a separate file system directory.
For example, the files of cells 1n4372 and 1n4376 under the
diode library reside in directories
/share/library/diode/1n4372/ and
/share/library/diode/1n4376/ respectively.
■ Under each cell, there are files of different views, each set
residing in a separate file system directory.
For example, the files related to the symbol view sym_1 reside
in directory
/share/library/diode/1n4372/sym_1/.
In addition, there are library-specific files that reside in the library
directory.
A Design Entry HDL library can contain designs or parts, both share
the same basic Library>Cell>View structure.
Note: Design Entry HDL power sources are supported in DE
HDL-PSpice flow:
■ A power symbol that has the HDL_POWER and VOLTAGE
property defined can be netlisted as a voltage source by
enabling a flag in PSpice.ini. The flag contains a keyword,
INCLUDE_POWERSOURCE, which should be equal to one. This
flag should be added in PSpice.ini under the [NETLIST
SETTING] section.
■ A power symbol that has the HDL_POWER property and the
VOLTAGE property, which is equal to zero, is netlisted as ground
source in DE HDL-PSpice Simulator flow.
■ To enable user-defined ground names as valid ground sources
in DE HDL-PSpice Simulator flow, define a flag in PSpice.ini
under the [NETLIST SETTING] section. The flag contains a
keyword, INCLUDE_GROUNDNODES, which should have
comma-separated user-defined ground names.
