Embodiment Construction

[0039] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0040] The present invention provides a system for Ieee1588 module simulation in OTN, which is used to simulate and test the Ieee1588 module. The system includes an incentive generation module, a mixing module, a simulation system access module, a simulation system output module, a separation module and scoring The scoreboard includes a first scoreboard and a second scoreboard.

[0041] The stimulus generation module is used to generate Ethernet frames and ptp frames based on the requirements of the simulation test. For the Ieee1588 module, it mainly processes Ethernet-based ptp frames. For DUT (Device UnderTest, the module under test), it is obtained from the Ethernet The frame passes through the DUT and is then sent to the OTN device, so the frame entering the DUT is a mixture of Ethernet frames and ptp frames, so the stimulus generation module is required ...

Abstract

The invention relates to the field of logic verification development and discloses a system for simulating an Ieee1588 module in an OTN (Optical Transport Network). The invention also discloses a method for simulating the Ieee1588 module in the OTN (Optical Transport Network). The method comprises the steps that S1, an excitation generation module generates Ethernet frames and ptp frames; S2, the ptp frames are mixed with the Ethernet frames, thereby forming mixed Ethernet frames; S3, a simulation system access module captures the mixed Ethernet frames and generates a drive signal for driving DUT, and the simulation system access module captures the Ethernet frames and the ptp frames generated by the excitation generation module and sends the Ethernet frames and the ptp frames to scoring boards; S4, a simulation system output module monitors and obtains the mixed Ethernet frames output by the DUT; S5, the mixed Ethernet frames output by the DUT are separated, thereby obtaining the Ethernet frames and the ptp frames; and S6, in the scoring boards, the separated Ethernet frames are compared with the Ethernet frames generated by the excitation generation module, and the separated ptp frames are compared with the ptp frames generated by the excitation generation module. The system and the method are high in multiplexing.

Description

technical field [0001] The invention relates to the field of logic verification development, in particular to a system for Ieee1588 module simulation in OTN and a method for Ieee1588 module simulation in OTN. Background technique [0002] In the open field of OTN (Optical Transport Network, Optical Transport Network) logic, the simulation work of the Ieee1588 module has always been a cumbersome, repetitive, delicate and heavy workload. Ieee1588 is a precision clock for network measurement and control systems Synchronization protocol standard, referred to as PTP (Precision Time Protocol, precision clock synchronization protocol). Usually, for different simulation levels, different simulation verification environments need to be written, and the reusability of these simulation verification environments is low, so in the actual simulation work, more simulation resources need to be consumed, and these simulation resources Maintenance is quite cumbersome.
