Latest Patents

One of Schaefer's latest patents is titled "Logic analysis subsystem in a time-sliced emulator." This invention introduces a logic analysis subsystem that reconstructs signals previously reduced by the compiler, allowing users to set breakpoints and triggers using these signals and others from the emulated circuit. The invention includes a logic analysis subsystem compiler, which can be a part of the regular emulator compiler or a standalone entity. It compiles the design for emulation and generates control instructions for the hardware, which is integrated into the time-sliced emulator. This subsystem enables the reconstruction of previously reduced signals, enhancing the user's ability to analyze the emulated circuit.

Another significant patent is "Software reconfigurable target I/O in a circuit emulation system." This invention describes a time-sliced hardware-based emulator that features programmable I/O assignments, DC voltage levels, pull-up or pull-down resistors, and more. The emulator connects to a target system via a specially designed Pod System Interface (PSI) and a Pod User Interface (PUI). This setup allows for efficient data transfer between the emulator and the target system, utilizing multiplexing techniques to manage data flow effectively.
