Overview

SCI-Compiler is a professional FPGA development environment that requires adequate system resources to operate efficiently. The requirements vary significantly depending on whether you plan to compile locally or use the remote compilation service.

Two deployment scenarios:

  • SCI-Compiler only (using remote compilation)
  • SCI-Compiler + Local FPGA tools (Xilinx Vivado or Intel Quartus)

Operating System Requirements

Supported Operating Systems

Operating System Support Status Notes
Windows 11 (64-bit) ✓ REQUIRED Only supported OS for SCI-Compiler
Windows 10 (64-bit) ✗ Not supported No longer compatible
Windows 8.1 (64-bit) ✗ Not supported No longer compatible
Linux ⚠ SciSDK only SCI-Compiler not available, only SciSDK library
macOS ⚠ SciSDK only SCI-Compiler not available, only SciSDK library

Important: Only Windows 11 64-bit is supported for running SCI-Compiler. 32-bit operating systems and older Windows versions are not compatible.

Note: While SCI-Compiler requires Windows 11, the SciSDK library (for reading data from compiled firmware) is available for Linux and macOS. You can develop firmware on Windows 11 and deploy data acquisition software on Linux/macOS using SciSDK.

Windows Version Requirements

Required: Windows 11 Professional or Home 64-bit

  • Professional edition recommended for business/laboratory use
  • Home edition acceptable for personal/educational use
  • Ensure all Windows updates are installed
  • Enable virtualization support in BIOS (for Vivado/Quartus)
  • Latest Windows 11 version (22H2 or later) recommended

Processor Requirements

Minimum Requirements

Component Specification
Architecture x86-64 (64-bit)
Cores 4 cores / 8 threads
Base Clock 2.5 GHz or higher
Example CPUs Intel Core i7 (7th gen or later), AMD Ryzen 5 3600 or equivalent
Component Specification
Processor Intel Core Ultra 9 or Intel Core i9 (12th gen or later)
Cores 8-16 cores / 16-32 threads
Base Clock 3.0 GHz or higher
Alternative AMD Ryzen 9 5900X or higher

Why Powerful CPUs Matter

FPGA compilation is extremely CPU-intensive:

  • Synthesis uses 4-8 threads heavily
  • Place & Route can utilize 12+ threads
  • Compilation time scales nearly linearly with core count

Performance comparison (typical project):

Processor Cores Compilation Time
Intel Core i5-7400 4C/4T 90-120 minutes
Intel Core i7-10700 8C/16T 45-60 minutes
Intel Core i9-12900K 16C/24T 25-35 minutes
Intel Core Ultra 9 185H 16C/22T 20-30 minutes
AMD Ryzen 9 5950X 16C/32T 20-28 minutes

Tip: Use remote compilation if your PC has limited CPU performance.

Memory (RAM) Requirements

SCI-Compiler Only (Remote Compilation)

Configuration RAM Required
Minimum 8 GB
Recommended 16 GB

Suitable for:

  • Design entry and editing
  • Simulation
  • Resource Explorer
  • Remote compilation workflow

SCI-Compiler + Local FPGA Tools

Configuration RAM Required Use Case
Minimum 16 GB Small designs, basic projects
Recommended 32 GB Medium to large designs
Optimal 64 GB Very large designs, parallel compilations

Why More RAM Helps

Vivado/Quartus memory usage during compilation:

  • Small designs: 4-8 GB
  • Medium designs: 8-16 GB
  • Large designs: 16-32 GB
  • Very large designs: 32-48 GB

Additional memory needs:

  • Windows OS: 4-6 GB
  • SCI-Compiler: 2-4 GB
  • Browser, editors, etc.: 2-4 GB

With 32 GB RAM:

  • Compile while keeping SCI-Compiler open
  • Run simulations simultaneously
  • Browse documentation without slowdowns
  • Operating system has adequate cache

Warning: Insufficient RAM causes:

  • Extreme slowdowns (disk swapping)
  • Compilation failures (out-of-memory errors)
  • System instability

  2. Allocate more CPU cores in tool settings
  3. Increase RAM to avoid disk swapping
  4. Disable antivirus scanning for project folders (whitelist)
  5. Close unnecessary applications during compilation
  6. Use local disk (not network drives)

Save Disk Space

  1. Delete old project builds regularly
  2. Use remote compilation (no local Vivado install)
  3. Archive completed projects to HDD/external storage
  4. Disable Vivado debug files in project settings
  5. Clean temp files after compilation

Improve Stability

  1. Keep Windows updated
  2. Install latest USB drivers
  3. Use quality USB cables
  4. Avoid USB hubs
  5. Disable USB power saving in Windows settings

Upgrading from Legacy Systems

Migrating from Older PCs

If upgrading from an older system:

Old System Upgrade Priority
< 8 GB RAM 1. Upgrade to 32 GB
HDD only 1. Add NVMe SSD
4 cores 2. Upgrade to 8+ core CPU
Windows 7/8 1. Upgrade to Windows 11

Typical upgrade path:

  1. Install NVMe SSD (biggest impact on compilation speed)
  2. Upgrade RAM to 32 GB (eliminates swapping)
  3. Upgrade CPU to modern 8+ core (if motherboard allows)
  4. Upgrade to Windows 11 (better compatibility)
