1.8. Appendix
Device Used and Quartus Tool Version
For interoperability with ADC AD9208, two device variants of Intel® Stratix® 10 are used.
- For lane rates above 15G and up to 16G: 1SG280HU1F50E1VGS1 (Transceiver speed grade -1 device)
- For lane rates of 15G and lower: 1SG280HU2F50E2VGS1 (Transceiver speed grade -2 device)
Except for the modes LMF 821/822/841/842, these modes were generated in Transceiver speed grade -1 device in order to achieve timing.
Intel® Quartus® Prime Pro Edition software version 17.1 IR2 Build 50 is used for compilation of designs.
Timing Closure Details
To achieve timing closure, the I/O ports of Assembler (Assembler to JESD IP) & De-assembler (JESD IP to De-assembler) were pipelined for the test modes LMF 882 & 884.
The following Analysis/Fitter settings were added to the qsf file to close the timing requirements for the variants LMF 882 & LMF 884.
Compiler Setting | Value Used | Default Value |
---|---|---|
Optimization Technique | Speed | Balanced |
Optimization Mode | Aggressive | Balanced |
Router Timing Optimization Level | Maximum | Normal |
Auto Packed Registers | Normal | Auto |
Physical Synthesis | ON | OFF |
Restructure Multipliers | OFF | Auto |
Fitter Initial Placement Seed | 1-10 | 1 |
The modes enlisted here have not been validated in this interoperability test, but they are supported by the ADC. These have been tabulated here for future reference.
