Abstract: A computer-based simulation process executes a checkpoint operation while simulating behavior of an electronic circuit by forking an active checkpoint process having the same state as the original simulation process. While simulation time for the simulation process continues to increase after executing the checkpoint operation, simulation time for the checkpoint process remains unchanged so that the checkpoint process remains in the state of the simulation at the simulation time it executed the checkpoint operation (the “checkpoint time”). When the checkpoint process subsequently receives a request to resume simulating the circuit, it forks a new simulation process that mimics the original simulation process as of checkpoint time, and the new simulation process then begins to advance its simulation time, thereby enabling it to re-simulate behavior of the electronic circuit previously simulated by the original simulation process starting from the checkpoint time.

Abstract: Emulation systems and method involving invalidating blocks of translated code in emulation of a target system on a host system in are disclosed. One or more blocks of target system code are translated by the host system to produce one or more corresponding blocks of translated code. The host system uses one or more native target system instructions as hints to invalidate or potentially invalidate one or more blocks of translated code. Blocks containing such hints cause the host system to mark some or all of the one or more blocks of translated code as potentially invalid. The potentially invalid blocks may be re-translated immediately. Alternatively, the potentially invalid blocks may be checked to see if the code in these blocks has been modified. If the code has been modified, corresponding blocks of target code may be re-translated.

Abstract: Included among the many structures described herein are photonic bandgap fibers designed to provide a desired dispersion spectrum. Additionally, designs for achieving wide transmission bands and lower transmission loss are also discussed. For example, in some fiber designs, smaller dimensions of high index material in the cladding and large core size provide small flat dispersion over a wide spectral range. In other examples, the thickness of the high index ring-shaped region closest to the core has sufficiently large dimensions to provide negative dispersion or zero dispersion at a desired wavelength. Additionally, low index cladding features distributed along concentric rings or circles may be used for achieving wide bandgaps.
