Low-level design is created based on the high-level design. LLD describes the class diagrams with the methods and relations between classes and program specs. It describes the modules so that the programmer can directly code the program from the document. A good low-level design document makes the program easy to develop when proper analysis is ...
In neuroscience, low-level would relate to the functioning of a cell (or part of a cell, or molecule) and high level to the overall function or activity of a neural system. [1] In documentation, a high-level document contains the executive summary, the low-level documents the technical specifications.
The module design phase can also be referred to as low-level design. The designed system is broken up into smaller units or modules and each of them is explained so that the programmer can start coding directly. The low-level design document or program specifications will contain a detailed functional logic of the module, in pseudocode:
The application level design identifies and specifies all of the software components (partitions) needed in the design. Static models, dynamic models, behavioral models, and the rationale component are built for the objects at the application level. These specifications become the requirements on the next level of design – the low-level design.
A software design description (a.k.a. software design document or SDD; just design document; also Software Design Specification) is a representation of a software design that is to be used for recording design information, addressing various design concerns, and communicating that information to the design’s stakeholders.
Exit criteria are the criteria or requirements which must be met to complete a specific process. For example, for Fagan inspections the low-level document must comply with specific exit criteria (as specified in the high-level document) before the development process can be taken to the next phase.

Software design usually is directed by goals for the resulting system and involves problem-solving and planning – including both high-level software architecture and low-level component and algorithm design. In terms of the waterfall development process, software design is the activity of following requirements specification and before coding ...
