Private Static Attributes

static constexpr size_t newest_supported_compatible_until = bss_hw_params::cube_ethernet::bitfile_compatible_until

static constexpr size_t oldest_supported_version = 0

Numbers to compare against bitfile protocol version.

There are 5 scenarios (newer covers new changes as well as outdated partners) 1: Software is newer than biftile and still compatible 2: Software is newer than biftile but incompatible 3: FPGA bitfile is newer than software and still compatible 4: FPGA bitfile is newer than software but incompatible 5: Both are head

The FPGA returns two numbers

• version: Integer automatically incrementing with each change to the bitfile

• compatible_until: Integer manually incrementing when bitfile introduces breaking feature

We can now cover all 5 cases by comparing these two numbers as follows

• oldest_supported_version: manually set to last known bitfile version with breaking change

• newest_supported_compatible_until: identical to current head bitfile compatible_until

oldest_supported_version needs to be lesser or equal to version and newest_supported_compatible_until needs to be greater or equal to compatible_until Cases 1, 3 and 5 fulfill these conditions whereas 2 and 4 do not

template<typename Connection>
class hxcomm::Stream

#include <stream.h>

Interface definition as to how each connection can be interacted with.

The user is supposed to only be able to construct and destroy Connection handles on its own. Interaction is mitigated by the corresponding Stream<Connection>-object which is constructed by execute_messages

Note: The Stream<Connection>-interface is intended for hxcomm and its internal testing routines and not meant to be relied upon in upper layers!

Instead, interaction with upper layers happens via execute_messages(connection, messages). Here the specialized versions of Stream<Connection> that have to be derived from this class are instantiated.

By convention, Stream<Connection> is befriended by Connection and calls private functions of the same signature as its interface.

tparam Connection
