Cadence Showcases World's First 128GT/s PCIe 7.0 IP Over Optics

PCI-SIG DevCon 2024 was a great success for Cadence. We posted the blog, Cadence Demonstrates Complete PCIe 7.0 Solution at PCI-SIG DevCon ‘24 a day before the event to advertise our IP solutions for PCIe 7.0, which resulted in a lot of extra traffic at our booth. All of the attendees were excited to see Cadence demonstrate the robustness of 128GT/s PCIe 7.0 IP's TX and RX capabilities over a real-world, low-latency, non-retimed, linear optics connector. We achieved and maintained a consistent, impressive pre-FEC BER of ~3E-8 (PCIe spec requires 1E-6) for the entire duration of the event, spanning over two full days with no breaks. This provides an ample margin for RS FEC. As seen in the picture below, the receiver Eye PAM4 histograms have good linearity and margin. This is the world’s first stable demonstration of 128 GT/s TX and RX over off-the-shelf optical connectors—by far the main attraction of DevCon this year.

HBM3E: All About Bandwidth

The rapid rise in size and sophistication of AI/ML training models requires increasingly powerful hardware deployed in the data center and at the network edge. This growth in complexity and data stresses the existing infrastructure, driving the need for new and innovative processor architectures and associated memory subsystems. For example, even GPT-3 at 175 billion parameters is stressing the bandwidth, capacity, training time, and power of the most advanced GPUs on the market.

To this end, Cadence has shown our HBM3E memory subsystem running at 12.4Gbps at nominal voltages, demonstrating the PHY’s robustness and performance margin. The production version of our latest HBM3E PHY supports DRAM speeds of up to 10.4Gbps or 1.33TB/s per DRAM device. This speed represents a >1.6X bandwidth increase over the previous generation, making it ideal for LLM training.

Cadence has been the HBM performance leader since 2021, when we announced our first 8.4Gbps HBM3E PHY supporting >1TB/s of memory bandwidth per HBM DRAM. Customers building advanced AI processors have used this speed while building margin into their systems. Recall that HBM3E is a 3D stacked DRAM with 1024-bit wide data (16 64-bit channels). While this wide data bus enables high data transfer, routing these signals requires interposer technology (2.5D) capable of routing close to 2000 signals (data and control), including silicon, RDL, and silicon bridges.

The interposer design is critical for the system to operate at these data rates. Cadence provides 2.5D reference designs, including the interposer and package, as part of our standard IP package. As demonstrated in our test silicon, these designs give customers confidence they will meet their memory bandwidth requirements. The reference design is also a good starting point, helping to reduce development time and risk. Our expert SI/PI and system engineers work closely with customers to analyze their channels to ensure the best system performance.

Even as HBM3E delivers the highest memory bandwidth today, the industry keeps pushing forward. JEDEC recently announced that HBM4the next version of the HBM DRAM standard, is nearing completion. JEDEC calls HBM4 an “evolutionary step beyond the currently published HBM3 standard.” They also claim HBM4 “enhancements are vital for applications that require efficient handling of large datasets and complex calculations.” HBM4 will support AI training applications, high-performance computing (HPC), and high-end graphics cards.

Cadence will continue to push the HBM performance boundaries to ensure designers of these data-intensive systems can take advantage of the highest memory bandwidth available.

Innovus 'syntax error'. but works in Genus


Hi everyone,

I'm new to using Innovus and I'm encountering an issue while trying to perform the "init_design" command. My goal is to perform the place and route. Here are the commands I'm using:

``
set init_verilog ./test.v
set init_top_cell TEST
set init_pwr_net {VDD VDD_2 VDD_3}
set init_gnd_net {VSS VSSA}
set init_lef_file { /home/laumecha/uw_openroad_free45/pdk/Drexel-ECEC575/Encounter/NangateOpenCellLibrary/Back_End/lef/NangateOpenCellLibrary.lef}
set init_mmmc_file {./viewDefinition.tcl}
init_design
```

However, I receive the following error:

```

**ERROR: (IMPVL-902):   Failed to read netlist ./test.v. See previous error messages for details.  Resolve the issues and reload the design.
```

However, the file works perfectly in Genus.


It seems there is a syntax error in my Verilog file at line 16, but I'm not sure how to resolve it. Any guidance or suggestions would be greatly appreciated.

UPF 3.1 / Genus - Cannot find any instance for scope

Hi, I'm using genus (Version 21.14-s082_1) to synthesis a VHDL-design with multiple power-domains. After reading the power intent file and calling 'apply_power_intent',  I get the following warning:

Warning : Potential problem while applying power intent of 1801 file. [1801-99]
: Cannot find any instance for scope '/:CHIP_TOP'. Rest of commands in this scope will be skipped (set_scope:../../upf/CHIP_TOP.upf:2).
: Check the power intent. If the scenario is expected, this message can be ignored.

The fist two lines of CHIP_TOP.upf:

upf_version 3.1
set_scope :CHIP_TOP

I simulated the same  UPF and VHDL files with Xeclium and was able to verify all the IEEE1801/UPF aspects I need without any problems. I don't know, why genus is having a problem with the 'scope'.
In genus, after getting the warning, running 'set_db power_domain:CHIP_TOP/BLOCK_A/PD_CORE_D .library_domain PD0V5' returns the following error:

Error : <Start> word is not recognized. [TUI-182] [set_db]
: 'power_domain:CHIP_TOP/BLOCK/PD_CORE_D' is not a recognized object/attribute. Type 'help root:' to get a list of all supported objects and attributes.
: Check if the given <Start> word is a valid object_type, object or attribute.

Running 'commit_power_intent' gives me:

Started inserting low power cells...
====================================
Info : Command 'commit_power_intent' cannot proceed as there are no power domains present. [CPI-507]
: Design with no power domains is 'design:CHIP_TOP'.
Completed inserting low power cells (runtime 0.00).
====================================================

I'm suspecting that the problem lies in 'set_scope' and VHDL. I never had such problems with Verilog. I tried every way to reference the hierarchy in the code and now I'm at my wit's end and I need your help o/
How to set the scope with 'set_scope' in UPD 3.1 to the toplevel in VHDL, so that genus accepts it? Or is the problem caused by something else?

Best,

Iqbal

Destructive form of "cons" - efficiently prepending an item to a procedure's argument which is a list

Hello,

I was looking to destructively and efficiently modify a list that was passed in as an argument to a procedure, by prepending an item to the list.

I noticed that cons lets you do this efficiently, but the operation is non-destructive. Hence this wouldn't work if you are trying to modify a function's list parameter in place.

Here is an example of trying to add "0" to the front of a list:

procedure( attempt_to_prepend_list(l elem)
    l = cons(elem l)
)
a = list(1 2 3)
==> (1 2 3)
attempt_to_prepend_list(a 0)
==> (0 1 2 3)
a
==> (1 2 3)
As we can see, the original list is not prepended.
Here is a function though which achieves the desired result while being efficient. Namely, the following function does not create any new lists and only uses fast methods like cons, rplacd, and rplaca
procedure( prepend_list(l elem)
    ; cons(car(l) cdr(l)) results in a new list with the car(l) duplicated
    ; we then replace the cdr of l so that we are now pointing to this new list
    rplacd(l cons(car(l) cdr(l)))

    ; we replace the previously duplicated car(l) with the element we want
    rplaca(l elem)
)
a = list(1 2 3)
==> (1 2 3)
prepend_list(a 0)
==> (0 1 2 3)
a
==> (0 1 2 3)
This works for me, but I find it surprising there is no built-in function to do this. Am I perhaps overlooking something in the documentation? I know that tconc is an efficient and destructive way to append items to the end of a list, but there isn't an equivalent for the front of the list?

Genus: Generated netlist doesn't define subckts

Dear all, 

I'm trying to perform an LVS check using Calibre between a layout that was generated by Innovus and the initial netlist generated by Genus. However, once I hit Run LVS on Calibre, it reports the following warnings and recommends to stop the process:

Source netlist references but does not define more than 10 subckts:
DFD1BWP7T
DFKCND1BWP7T
DFKCNQD1BWP7T
DFKSND1BWP7T
DFQD1BWP7T
IND2D0BWP7T
INR2D0BWP7T
INVD0BWP7T
INVD2P5BWP7T
IOA21D0BWP7T
... (and more)

If I proceed the LVS process it shows lots of errors as shown in the following image:

Why Genus doesn't include the definition of those sub circuits in the generated netlist? Is this related to Flat/Hierarchy netlisting? 

I have included my Genus scripts as well as the generated netlist in the attachments (and here - if attachment don't work).

Many thanks,

Conformal LEC can't finish at analyze abort step. How do I proceed?

Hi Cadence & forumers, 

I am running a conformal LEC with a flattened netlist against RTL. 

The run hang for 5 days at the "analyze abort" step which is automatically launched by the compare. 

The netlist is flattened at some levels so hierarchical flow which I tried didn't help much. The flattened/highly optimized netlist is from customer and the ultimate goal. How shall I proceed now? 

On the a side note, a test run with a hierarchical netlist from a simple DC "compile -map_effort medium" command finished after 1 day or so. 

Thank you!
