This chapter describes all functionality that is currently deprecated or legacy, and, in the former case, when it will be removed, including items removed in the current release. There are also suggestions on replacements.

7.1 Legacy in Simics 7

Functionality classified as legacy in Simics 7.

7.1.1 Product Features

Functionality	Notes
The `-echo` command line option can be used to include command invocations as part of Simics output, which can be directed to file
The script declaration system.	New code should use the target parameter framework.
The component system.	New code should use the blueprint framework.
DML 1.2	New code should use DML 1.4.
Haps	New code should use notifiers.
GNU make based module build system.	New modules should use CMake instead.
Ports and port interfaces.	New devices should use port objects.
The `[obj, "name"]` syntax for device connects.	New devices should use port objects and regular interfaces, e.g. use syntax `obj.port.name` or `obj.bank.name`.

7.1.2 CLI

Functionality	Notes
break-io	bp.bank.break is a replacement in most cases
unbreak-io	bp.bank.break and bp.delete is a replacement in most cases
trace-io	bp.bank.trace is a replacement in most cases
trace-io-setup	No replacement.
untrace-io	bp.bank.trace and bp.delete is a replacement in most cases
wait-for-io-break	bp.bank.wait-for is a replacement in most cases
restart-simics	It only works when running Simics locally.
The ports attribute (e.g. `dev.ports.HRESET.signal`).	Use port objects and the `port` or the `bank` sub-namespace (e.g. `dev.port.HRESET.iface.signal`).

7.1.3 Interfaces

`io_memory`	New code should use `transaction`

Modulo calculation in fixed sized arguments will be deprecated in Simics 7. In Simics 6, a warning will be printed when module calculation is required to fit into the type.
