1. A method for managing flow of commands from logic under test to a receiving component, the method comprising:
- determining a rate at which flow control signals are received by the logic under test from the receiving component over time, the flow control signals indicating that there is space available in a buffer in the receiving component to receive commands for performing transactions; and
using the determined rate of receipt of the flow control signals by the logic under test for managing flow of commands from the logic under test to the receiving component without waiting for actual processing of the flow control signals by the logic under test.

Abstract
Flow of commands from logic under test, such as an FPGA, to a receiving component, such as a component in a PCIe hierarchy, is managed. A rate at which flow control signals are received by the logic under test from the receiving component is determined, the flow control signals indicating that there is space available in a buffer in the receiving component for receiving commands. The determined rate of receipt of the flow control signals is used for managing flow of commands from the logic under test to the receiving component without waiting for actual processing of flow control signals by the logic under test.

11. A system for managing flow of commands from logic under test to a receiving component, the system comprising:
-
logic under test; and a receiving component receiving commands from the logic under test, wherein the receiving component transmits flow control signals to the logic under test indicating that there is space available in a buffer in the receiving component for receiving commands, and the logic under test manages flow of commands to the receiving component based on a determined rate of receipt of the flow control signals without waiting for actual processing of the flow control signals from the receiving component. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19, 20)
