Defacto’s SoC Compiler is a complete SoC integration platform multidimensional and pre-synthesis with a high level of automation taking in consideration all design information, including RTL, IP-XACT, timing constraints, power, physical, and test.
Before logic synthesis, SoC Compiler enables full implementation capabilities towards IP and connectivity insertion, design editing, views generation with real-time monitoring of the integration progress.
This enables SoC creation in minutes and maximizes design reuse from existing projects.
High Level Benefits
- Assist reaching best possible PPA combination within a tight schedule
- Bring more automation into SoC Integration flow before logic synthesis
- Augment existing front-end SoC assembly and integration flows towards a more unified integration process by considering several design collaterals RTL, IP-XACT, SDC, UPF, LEF/DEF, etc.
- Get up to 90% and higher of design reuse including RTL and design collaterals
- Easily migrate internal scripts and tools with the support of rich APIs high and low level: Tcl, Python, Perl, C++, Java, etc.
- Reduce drastically TAT and engineering effort by minimizing design iterations
- Enable non-experts to perform design engineering tasks (power, architecture, testing, etc.) through simple APIs
- Enables SoC creation even if design blocks and views are missing
High Level Key Features
- Multi-format IP cores insertion including Verilog, System Verilog, VHDL, IP-XACT 2009, IP-XACT 2014, even mixed and uncompleted.
- Automated and hierarchical connectivity insertion including System Verilog and IP-XACT interfaces
- Real-time monitoring of the SoC integration progress
- Physically, Power and Timing-aware integration process at RTL
- Design Reuse and Packaging of IP cores and subsystems.

SoC Compiler enables the SoC design assembly process with full support of IP-XACT standard in full compliance with RTL files. Several automated design “extraction, packaging and reuse” capabilities are provided. Extraction of the system memory map is also part of the SoC Compiler capabilities. Defacto is part of the Accellera committee for the definition of IP-XACT standard and an active member of the IP-XACT 2021 version

During the SoC integration process, SoC Compiler automates the management of power intent through an automated generation, update, promotion and demotion of UPF files. Power Intent Static Checks and UPF-vs-RTL coherency checks are also provided as part of the power integration process.
- Full language support: UPF 1.0 / 2.0 / 2.1 / 3.0 / 3.1
- Complete power intent checks including UPF linting and coherency checking with RTL and Liberty files.
- UPF Promotion to help promoting existing UPF files and generate a top level UPF file
- UPF Demotion to help extracting UPF files from hierarchical blocs & subsystems
- UPF Update as soon as a design change occurs
- UPF Generation from scratch
- From Excel (XLS) or custom template
- Ability to update XLS file post UPF modifications
Customer statement at DAC 2022: “This solution has proven its reliability and optimized performance. With simple API interactions, overall scripting process to integrate the features into our custom flow is smooth.”
SoC Compiler enables several clock management capabilities as part of the SoC integration process. Clock-tree exploration, checking and generation of timing constraints are provided, including demotion and promotion of SDC.
- Clock tree exploration
- Identification of clock sources and potential pin constraints
- Dedicated DRCs for master / generated clock path checks
- RTL vs. SDC Coherency Checks
- GUI based exploration and debug environment
- SDC update files whenever a design is modified
- SDC generation from scratch
- SDC demotion or extraction from the top level
- SDC promotion from different IPs to the top level
SoC Compiler enables the consideration of physical design information which are contained in LEF/DEF file to let the SoC integration process lead to better PPA results, in particular, reducing overall chip size area. Optimizing design for back-end will reduce the P&R effort by avoiding many iterations between Back-end and Front-end.
