"I'm My project for this summer is titled:In this blog, I'll walk you through the motivation behind the project, the implementation details, and what I achieved in integrating TCAM into the Chipyard SoC framework. "Integrating TCAM IP into Chipyard via MMIO and RoCC Interfaces." and I'm excited to share that I have been selected as a Clone OpenTCAMGenerate RTLIntegrate as Black Box - Use the generated RTL as a black box in your SoC, either as an MMIO peripheral or a RoCC accelerator."
"Missing TCAM Port in Design Generation: The TCAM module was not included in Digitop.scala, preventing the TCAM interface ports from appearing in the generated design hierarchy and making external signal connections impossible. Clock Frequency Timing Issues: Default 500 MHz clock frequency from pbus.fixedClockNode caused timing mismatches between SRAM updates, requiring reduction to 100 MHz for proper timing closure and SRAM operation."
Project integrates a Ternary Content Addressable Memory (TCAM) IP into the Chipyard SoC using MMIO and RoCC accelerator interfaces. The integration required generating TCAM RTL, using it as a black box peripheral, and adjusting build commands such as make tcam_rtl CONFIG=<your_config>. Key issues included a missing TCAM port in Digitop.scala preventing external connections, timing failures due to default 500 MHz pbus clock resolved by lowering to 100 MHz, and malformed OpenTCAM-generated Verilog requiring manual RTL fixes. RoCC command detection succeeded only after switching from cmd.valid to cmd.fire. Repository cloning and documentation setup enabled environment configuration.
