  • Patent number: 10282502
    Abstract: Technologies are provided for automatically performing multiple integrated circuit implementation runs with variations of input design constraints. Input design constraints can be automatically adjusted to create multiple modified versions of the design constraints. The multiple modified design constraints can be used to perform separate integrated circuit implementation runs for a given circuit design. Results of the multiple implementation runs can be analyzed, and a circuit implementation report can be generated based on the results of the runs performed with the various modified design constraints. In some embodiments, a circuit implementation recommendation can be generated based on the implementation run results. In at least some scenarios, the multiple implementation runs can be performed using multiple synthesis and implementation processes. The multiple synthesis and implementation processes can be distributed across one or more host computing devices.

  • Patent number: 10284460
    Abstract: Network packet tracing may be implemented on packet processors or other devices that perform packet processing. As network packets are received, a determination may be made as to whether tracing is enabled for the network packets. For those network packets with tracing enabled, trace information may be generated and the network packets modified to include the trace information such that forwarding decisions for the network packets ignore the trace information. Trace information indicate a packet processor as a location in a route traversed by the network packets and may include ingress and egress timestamps. Forwarding decisions may then be made and the network packets sent according to the forwarding decisions. Tracing may be enabled or disabled by packet processors for individual network packets. Trace information may also be truncated at a packet processor.

  • Patent number: 10218576
    Abstract: Technologies for performing controlled bandwidth expansion are described. For example, a storage server can receive a request from a client to read compressed data. The storage server can obtain individual storage units of the compressed data. The storage server can also obtain a compressed size and an uncompressed size for each of the storage units. The storage server can generate network packet content comprising the storage units and associated padding such that the size of the padding for a given storage is based on the uncompressed and compressed sizes of the given storage unit. The storage server can send the network packet content to the client in one or more network packets. The client can receive the network packets, discard the padding, and decompress the compressed data from the storage units.
