ASIC DDR PHY

The combination of Northwest Logic's Memory Controller Cores and ASIC DDR PHY is designed for use in ASICs requiring high memory throughput, high clock rates and full programmability.
Versions of the ASIC DDR PHY are available which support DDR3 1060, DDR2 1066, DDR 800, Mobile DDR 400, RLDRAM II 1066 Mbit/s/pin operation. Multi-mode versions are also available.
To ensure robust operation the DDR PHY uses a windowing data capture method, uses proven off-the-shelf DDR I/O and DLL, and supports ASIC-side ODT and calibrated output impedance.
The DDR PHY is specifically designed for flexibility. This in¬cludes a broad range of programmable features including vari¬ous timing parameters, termination settings and drive strengths.
The DDR PHY can be put into loopback for complete, at-speed production test. This test is orchestrated by the BIST Core in conjunction with the Memory Controller Core. The DDR PHY also supports DFT scan and JTAG boundary scan.

The combination of the Memory Controller Core and DDR PHY can be fully tested using Northwest Logic's Memory Test Core and Data Analyzer Core. The Memory Test Core provides a complete memory test using random and directed reads and writes. The Mem Test Analyzer Core provides access to the actual and expected memory test results for analysis.
The DDR PHY is delivered as a soft core with timing con¬straints. This enables the DDR PHY to be optimized for a tar¬get process and pinout.
Northwest Logic can provides DDR PHY related services includ¬ing DDR I/O and DLL replacement, process porting and DDR PHY hardening. Contact Northwest Logic for a quote.
