US 11,144,691 B2 · Virtual Ethernet mutable port group transactor

Abstract

Disclosed herein are example embodiments of methods, apparatus, and systems for transactors configured for use in a hardware emulation environment and designed to adapt to speed changes dynamically at runtime in addition to providing dynamic port mapping. Among the embodiments disclosed herein is an emulation system comprising one or more configurable hardware components (e.g., configurable logic blocks) configured to implement a mutable port group transactor in communication with a design under test being emulated by the emulation system. The emulation system can further comprise a host computer in communication with the emulator and configured to provide configuration commands to the emulator that alter the mutable port group transactor from a first configuration to a second configuration.

Dependent claims

An emulation system, comprising one or more configurable hardware components configured to implement a mutable port group transactor in communication with a design under test being emulated by the emulation system, the mutable port group transactor configured to:

based on a configuration, update one or more Ethernet ports in communication with the design under test;
and
communicate with the design under test at a communication speed that changes during runtime while the emulation system is emulating the design under test,
wherein the mutable port group transactor is compiled at compile time in accordance with a number of compile-time configurations that define one or more of:
a maximum number of lanes that can carry data streamed from and to the mutable port group transactor;
a maximum width of each lane that is interfaced with the mutable port group transactor;
or a maximum number of port interfaces that can be enabled during runtime through the mutable port group transactor.

4 more elements

A computer-implemented method comprising:

during an emulator configuration stage, transmitting configuration data adapted to configure hardware components of an emulator to operate as a mutable port group transactor;
during a runtime stage in which the emulator is emulating a design under test, transmitting runtime configuration data to the hardware components implementing the mutable port group;
during the runtime stage, altering one or more of a number of ports, a number of active lanes of one or more ports, a lane size of one or more ports, or a transmission speed of one or more ports in accordance with the runtime configuration data;
and
based on the runtime configuration data, updating one or more Ethernet ports during the runtime stage in accordance with the runtime configuration data,
wherein the configuration data causes the mutable port group transactor to have one or more of:
a user-defined maximum number of lanes that can carry data streamed from and to the mutable port group transactor, a maximum width of a single lane of each port that is interfaced from the mutable port group transactor, or a maximum number of port interfaces that can be enabled during runtime through the mutable port group transactor.

4 more elements

One or more non-transitory computer-readable media storing computer-executable instructions, which when executed by a computer, cause the computer to:

during an emulator configuration stage, transmit configuration data adapted to configure hardware components of an emulator to operate as a mutable port group transactor;
during a runtime stage in which the emulator is emulating a design under test, transmit runtime configuration data to the hardware components implementing the mutable port group;
and
based on the runtime configuration data, updating one or more Ethernet ports and communicating with the design under test at a communication speed that changes during the runtime stage while the emulator is emulating the design under test,
wherein the configuration data causes the mutable port group transactor to have one or more of:
a user-defined maximum number of lanes that can carry data streamed from and to the mutable port group transactor, a maximum width of each that is interfaced from the mutable port group transactor, and a maximum number of port interfaces that can be enabled during runtime through the mutable port group transactor.
