Photonic integrated circuit simulation with CMLs

Learn how circuit designers use CMLs to simulate photonic integrated circuits. 

INTERCONNECT CML

Compact model libraries generated by CML Compiler are installed in INTERCONNECT. The circuit designer leverages all the capabilities of INTERCONNECT for photonic circuit simulation. This library can also be used for INTERCONNECT-Virtuoso EPDA co-simulation for electrical and photonic simulations.

• Lumerical INTERCONNECT
• Install CML in INTERCONNECT
• Virtuoso interoperability - INTERCONNECT

Verilog-A CML (in Cadence Virtuoso)

Verilog-A CMLs generated by CML Compiler can be used in EPDA enabled Cadence Virtuoso for electrical and optical simulations.

• Virtuoso interoperability - Photonic Verilog-A
