of an emulated operating system. Instead of proliferating things like
SUSE_VERSION_REQD, NETBSD_VERSION_REQD, SOLARIS_VERSION_REQD, etc., a
package can say:
EMUL_REQD= suse>=9.1 netbsd>=2.0 solaris>=10
all in one, succinct line.
binary-only packages that require binary "emulation" on the native
operating system. Please see pkgsrc/mk/emulator/README for more
details.
* Teach the plist framework to automatically use any existing
PLIST.${EMUL_PLATFORM} as part of the default PLIST_SRC definition.
* Convert all of the binary-only packages in pkgsrc to use the
emulator framework. Most of them have been tested to install and
deinstall correctly. This involves the following cleanup actions:
* Remove use of custom PLIST code and use PLIST.${EMUL_PLATFORM}
more consistently.
* Simplify packages by using default INSTALL and DEINSTALL scripts
instead of custom INSTALL/DEINSTALL code.
* Remove "SUSE_COMPAT32" and "PKG_OPTIONS.suse" from pkgsrc.
Packages only need to state exactly which emulations they support,
and the framework handles any i386-on-x86_64 or sparc-on-sparc64
uses.
* Remove "USE_NATIVE_LINUX" from pkgsrc. The framework will
automatically detect when the package is installing on Linux.
Specific changes to packages include:
* Bump the PKGREVISIONs for all of the suse100* and suse91* packages
due to changes in the +INSTALL/+DEINSTALL scripts used in all
of the packages.
* Remove pkgsrc/emulators/suse_linux, which is unused by any
packages.
* cad/lc -- remove custom code to create the distinfo file for
all supported platforms; just use "emul-fetch" and "emul-distinfo"
instead.
* lang/Cg-compiler -- install the shared libraries under ${EMULDIR}
instead of ${PREFIX}/lib so that compiled programs will find
the shared libraries.
* mail/thunderbird-bin-nightly -- update to latest binary
distributions for supported platforms.
* multimedia/ns-flash -- update Linux version to 9.0.48 as the
older version is no longer available for interactive fetch.
* security/uvscan -- set LD_LIBRARY_PATH explicitly so that
it's not necessary to install library symlinks into
${EMULDIR}/usr/local/lib.
* www/firefox-bin-flash -- update Linux version to 9.0.48 as the
older version is no longer available for interactive fetch.
LC is simulation tool for the analysis of the electromagnetic
properties of electrical interconnects. The full three-dimensional
circuit is modeled, so all interactions are automatically included in
the solution. The model can be excited by numerous types of waveforms,
and the transient response measured using common values such as
voltage and current. Circuit parameters such as inductance,
capacitance, and impedance can be derived from the transient response,
and frequency-domain results such as S-parameters can also be
calculated. Far field radiation patterns can be obtained.
LC is primarily an electromagnetic simulation and uses the
Finite-Difference Time-Domain (FD-TD) technique. FD-TD is a full wave
explicit solution of Maxwell's equations in three dimensions. In FD-TD,
the rectangular volume enclosing the model is discretized into a large
number of small cells, which may be uniformly-sized, or may vary in size
within the simulation space. The dielectric, permeable, lossy, and
conducting material properties of each cell are incorporated into the
field updates, which are performed iteratively in small time steps.
An interface between the electromagnetic simulation and the circuit
simulation program SPICE is available within LC. This allows the user
to add arbitrary SPICE circuits, such as drivers and loads, into the
interconnect model. The interconnect performance is calculated using
FD-TD while the lumped-element circuits are evaluated by SPICE.
