FPGA Alternatives During Shortages

The semiconductor supply disruptions experienced in recent years fundamentally changed how engineers approach FPGA selection. For decades, FPGA design decisions were driven primarily by technical requirements such as logic density, DSP capability, transceiver bandwidth, and power consumption. During periods of supply shortages, however, availability itself became a critical design parameter. Many development teams discovered that an ideal FPGA architecture provides little value if lead times extend beyond project schedules or production commitments.

As a result, alternative FPGA evaluation has evolved into a strategic engineering discipline rather than an emergency procurement exercise. Successful substitution requires understanding architectural compatibility, development tool migration, performance trade-offs, and long-term supply stability.

Why FPGA Shortages Create Unique Challenges

Unlike standard microcontrollers, FPGA replacement is rarely a simple pin-to-pin exercise.

A typical FPGA design may depend on:

• Logic architecture

• DSP resources

• Embedded memory

• Clocking structures

• High-speed transceivers

• Vendor IP cores

• Development tools

Consequently, replacing an unavailable FPGA often affects both hardware and firmware development.

For example, migrating from a mid-range communication FPGA may require:

• PCB modifications

• HDL adjustments

• Timing revalidation

• Signal integrity testing

• Regulatory recertification

The cost of redesign frequently exceeds the component cost itself.

Evaluating FPGA Substitution Risk

Before considering alternatives, engineers should classify the design according to resource dependency.

Low-Risk Designs

Typically include:

• GPIO expansion

• Industrial I/O control

• Basic protocol conversion

• Timing generation

These applications generally consume:

Alternative devices can often be implemented with limited redesign effort.

Medium-Risk Designs

Examples:

• Motor control

• Industrial networking

• Machine vision preprocessing

Typical resource utilization:

Migration usually requires partial verification and timing optimization.

High-Risk Designs

Examples:

• 5G baseband systems

• AI accelerators

• Radar processing

• High-speed networking

Characteristics:

• Extensive DSP usage

• Heavy transceiver dependency

• Complex IP integration

These designs often require substantial engineering effort during migration.

AMD Xilinx to Intel FPGA Alternatives

One of the most common shortage scenarios involves substituting AMD Xilinx devices with Intel FPGA products.

Representative comparisons:

Although resource specifications may appear similar, direct migration requires careful evaluation.

Key differences include:

• DSP architecture

• Embedded memory organization

• Clocking resources

• Toolchain workflows

For communication systems relying on proprietary IP, migration complexity can increase significantly.

Intel FPGA to AMD Alternatives

Intel FPGA shortages have also prompted reverse migration efforts.

Typical alternatives:

In industrial automation projects, such migrations are often feasible because protocol processing and control functions tend to rely more heavily on HDL logic than vendor-specific acceleration features.

Emerging FPGA Suppliers as Alternative Sources

The FPGA market has become increasingly diversified.

Several vendors now provide viable alternatives for selected applications.

Microchip PolarFire

Applications:

• Industrial automation

• Aerospace systems

• Security-sensitive designs

Advantages:

• Low static power

• Non-volatile configuration

• Strong supply continuity

Representative comparison:

PolarFire devices have become increasingly attractive during shortages affecting larger FPGA vendors.

Lattice Semiconductor

Applications:

• Industrial control

• Edge processing

• Sensor aggregation

Advantages:

• Low power

• Competitive availability

• Small form factors

Popular families:

• ECP5

• CertusPro-NX

• Avant

These devices are often suitable replacements for lower-end and mid-range FPGA designs.

Gowin FPGA

Applications:

• Consumer electronics

• Display control

• Entry-level industrial products

Advantages:

• Competitive pricing

• Availability during shortages

Limitations:

• Smaller ecosystem

• Reduced third-party IP availability

Nevertheless, certain industrial projects have successfully adopted Gowin devices as temporary or permanent alternatives.

Resource-Based Substitution Methodology

A more reliable approach involves matching resources rather than part numbers.

Important parameters include:

Logic Resources

Target:

70–80% maximum utilization

Example:

Alternative target:

• 80K–120K LUT capacity

DSP Resources

Critical for:

• Motor control

• FFT processing

• AI acceleration

Example:

DSP shortages often create more migration problems than logic shortages.

Memory Resources

Evaluate:

• BRAM capacity

• Memory bandwidth

• External memory support

Many FPGA substitutions fail because memory architecture differences are overlooked.

Communication Equipment Case Study

Consider an industrial Ethernet gateway originally designed around an AMD Artix-7 FPGA.

System requirements:

• EtherCAT

• PROFINET

• Data logging

• Remote diagnostics

Resource utilization:

During a supply shortage, available alternatives may include:

• Intel Cyclone 10 GX

• Microchip PolarFire

• Lattice Avant

Evaluation criteria:

1. Logic capacity

2. Ethernet IP support

3. Development tool migration effort

4. Availability

In many cases, the engineering cost associated with migration outweighs modest differences in component pricing.

Software and Toolchain Considerations

Hardware compatibility alone does not guarantee a successful migration.

Development ecosystems include:

AMD

• Vivado

• Vitis

Intel

• Quartus Prime

• Platform Designer

Microchip

• Libero SoC

Lattice

• Radiant

• Propel

Migration effort frequently includes:

• HDL adaptation

• Constraint conversion

• Timing validation

• IP replacement

Projects heavily dependent on vendor-specific IP blocks typically face greater migration complexity.

Designing for Future Supply Flexibility

The most effective shortage mitigation strategy begins during initial design.

Recommended practices include:

Resource Margin

Maintain:

20–30% spare capacity

Avoid Vendor Lock-In

Where practical:

• Use portable HDL

• Minimize proprietary IP

• Standardize interfaces

Evaluate Multiple Suppliers Early

Create feasibility studies for:

• AMD alternatives

• Intel alternatives

• Microchip alternatives

This preparation significantly reduces redesign time if supply disruptions occur.

Lifecycle and Availability Planning

FPGA shortages often expose weaknesses in lifecycle planning.

Before committing to a device, engineers should evaluate:

• Product longevity programs

• Lead time history

• Supply-chain resilience

• Vendor roadmap stability

Industrial and communications equipment frequently remain in production for:

• 10–15 years

Therefore, long-term availability often becomes as important as technical performance.
