APPARATUS AND METHODS FOR HIGH-SPEED DRIVERS
Apparatus and methods for high-speed drivers are provided herein. In certain embodiments, a high-speed driver multiplexes two or more data streams. The high-speed driver is implemented with a mux-then-driver topology that provides multiplexing in a predriver circuit. Thus, the multiplexer is eliminated from the full rate output path to relax timing. Driver amplitude control schemes are also disclosed in which a controllable driver includes a group of differential series source transistor (SST) driver slices that are connected in parallel with one another to drive a pair of output terminals, and a group of attenuator slices that are connected in parallel with one another across the pair of output terminals. Additionally, the controllable driver includes a control circuit that activates an attenuator slice for each SST driver slice that is decommissioned to provide output amplitude control.

Architecture and methodology for tuning clock phases to minimize latency in a serial interface
Embodiments disclosed herein describe systems and methods for tuning phases of interface clocks of ASICs in an emulation system for a low latency channel and to avoid read errors. During a bring-up time (e.g., powering up) of the emulation system, one or more training processors may execute a software application to iteratively tune the phases of the interface clocks such that data is written to the interface buffers prior to being read out. To mitigate the problem of higher latency, the training processors may execute software application to tune the clock phases such that there is a small time lag between the writes and reads. The training processors may set the time lag to account for factors such as memory setup and hold, clock skews, clock jitters, and the predicted margin required to account for future clock drift due to carrying operating conditions.
