    Abstract: Methods and apparatus are disclosed for programming reconfigurable logic devices such as FPGAs in a multi-tenant server environment. In one example, a computing host includes one or more processors configured to execute a supervisor process and two or more user processes and a single FPGA integrated circuit configured into a plurality of partitions. The partitions include a host logic partition that is accessible only to the supervisor process executing on the computing host, and two or more accelerator partitions. Each of the accelerator partitions is configured to include a virtual debug unit with a logic analyzer that collects logic signals generated by logic within the respective accelerator partition and sends debug data indicating values of the logic signals to one of the user processes. In some examples, the host logic partitions and/or the accelerator partitions can be independently reprogrammed of each other within their respective portions of the single FPGA.

    Abstract: The following description is directed to a logic repository service supporting adaptable host logic. In one example, a method of a logic repository service can include receiving a first request to generate configuration data for configurable hardware using a specification for application logic. The method can include selecting a particular host logic shell from a group of host logic shells. The particular host logic shell can be used to encapsulate the application logic when the configurable hardware is configured. Configuration data for the configurable hardware can be generated. The configuration data can include data for implementing the application logic and at least a portion of the particular host logic shell. The method can include receiving a second request to download the configuration data to a host server computer comprising the configurable hardware. The configuration data can be transmitted to the host server computer in response to the second request.
