instTerms

Hi to all,

I am trying to write an SKILL code to create a schematic. In my code I use "instTerms" to obtain the terminals of an instantiated cell (Let's imagine it is a simple NMOS which is given as a predesigned cell), and then I will connect a wire to each of the terminals. When I run the whole code by command line, the returned terminals by "instTerms" are empty(nil) but when I try to debug it line by line it works properly. As more information, I call it for the instantiated cell, and I should say the cell is instantiated without any problem. This is just the problem of finding its terminals. 

Does anybody have any idea?

Thank you very much in advance.

USB4 Interoperability with Thunderbolt™︎ 3 (TBT3) Systems

One of the key goals for USB4 is to retain compatibility with the existing ecosystem of USB3.2, USB 2.0 and Thunderbolt  products, and the resulting connection scales to the best mutual capability of the devices being connected. USB4 is designed to work with older versions of USB and Thunderbolt . USB4 Fabric support high throughput interconnects of 10 Gbps (for Gen 2) and 20 Gbps (for Gen 3) and supports Thunderbolt 3-compatible rates of 10.3125 Gbps (for Gen 2) and 20.625 Gbps (for Gen 3). It becomes very important to verify the Thunderbolt  backward compatibility with the designs. Though the support of USB4 Interoperability with Thunderbolt  3 (TBT3) is optional in USB4 host or USB4 peripheral device and required USB4 Hub and USB4 Based Dock but it is very essential to work in the existing ecosystem. 

Few Main features of USB4 Interoperability with Thunderbolt  3 (TBT3) Systems

  • Support for Bi-Directional Pins & Retimers: TBT3 Active Cables can contain two bidirectional Re-timers which have the capability to send AT Responses on its RX channel. Router connected directly to such Retimer needs to support A Router that is connected directly to a bidirectional Re-timer shall support reception of Transactions on both TX and RX channels. 

  • Bounce Mechanism: This feature is used by Router to access the Register Space of a Cable Re-timer that can only be accessed by its Link Partner.
  • Asymmetric Negotiation: The Router which connects with Cable Retimers needs to follow Asymmetric TxFFE in Phase 5 of Lane Initialization. 
  • USB4 Link Transitions: In TBT3 mode, the configuration of two independent Single Lane Links can be used non-transient state or Single Lane Link just using the Lane1 Adapter.

Cadence has a mature USB4 Verification IP solution that can help in the verification of USB4 designs with TBT3. Cadence has taken an active part in the Cairo group that defined the USB4 specification and has created a comprehensive Verification IP that is being used by multiple members. If you plan to have a USB4-compatible design, you can reduce the risk of adopting new technology by using our proven and mature USB4 Verification IP. Please contact your Cadence local account team, for more details.

Find Routing problem (Route Vision) and quickly to fix these problems

The vision manager is good tool for routing check. but no quickly or effective  tool to fix or optimize this  problems to be optimized.

For example, parallel Gap less than preferred, min seg/Arc length,uncoupled diff-pair segs,and so on.

I only know use spread between voids to fix the non-optimized segs. in fact it is inefficient.

the parallel gap less than preferred is only to slice evry trace, its inefficient.

If i set the paraller gap less than 50um, Is there any tool to quickly fix these problems(gap less than 50um)?

For other problems,i can use tool to quickly fix the min seg/Arc length,uncoupled diff pair segs,accoding to select by polygon or select  by windows.

DDR5 UDIMM Evolution to Clock Buffered DIMMs (CUDIMM)

DDR5 is the latest generation of PCDDR memory that is used in a wide range of application like data centers, Laptops and personal computers, autonomous driving systems, servers, cloud computing, and gaming are now increasingly being used for AI applications with advances in memory bandwidth and density to allow DDR5 DIMMs (Dual Inline Memory Modules) to support densities higher then 256 GB per DIMM card. The highest speed DDR5 SDRAM devices can support data rates of up to 8800 MTps.

DDR5 SO-DIMMs and UDIMMs

One of the most recognized uses of PCDDR is with client devices like laptops and personal computers. These client devices mostly use two types of DDR5 DIMMs called SO-DIMM (Small Outline Dual Inline Memory Module) and UDIMM (Unbuffered Dual Inline Memory Module).

These types of DIMMs have no signal regeneration or buffering (which, for example, the Registering Clock Driver or the RCD does for clocks/command/control signals for a registered DIMMs). A typical 2-Rank UDIMM with x8 DDR5 SDRAM components has 8 or 10 components per rank depending on the system ECC (Error Correction Code) memory being part of the DIMM.

Why DDR5 Clock Buffer and CUDIMM?

Clocks are one of the most important signals for synchronous devices, and DDR5 SDRAMs are no exception. The host is responsible for the fanout to all the DRAM input ports, such as clocks for UDIMMs. Driving of all these DRAM clocks can put quite a bit of load on the host output drivers, thus affecting the signal quality, which can result in unexpected memory errors. This issue gets amplified when operating at the higher clock and data rates where the clock signals transition from one logic value to the next over a very short time. To solve these signal integrity issues with DRAM clocks, JEDEC has come up with a new type of DDR5 DIMM component that is called DDR5 clock buffer. Clock buffers can be used for both DDR5 SO-DIMMs and DDR5 UDIMMs. DDR5 UDIMMs that include a clock buffer component as part of the DIMM card are called DDR5 CUDIMMs (Clock Buffered UDIMMs).

DDR5 Clock Buffer Overview

DDR5 Clock Buffer is a simple logic device that takes in two sets of input clock pins and drives two sets of clock pins as output per channel. The clock buffer device can operate in three types of clock modes: -

  • PLL bypass mode: In this mode, the clock buffer just passes on the input clocks to output without any kind of signal buffering. The PLL bypass mode enabled CUDIMM devices behave like traditional UDIMMs without any buffering of the clocks. This is why it’s also referred to as legacy mode. Recommended CUDIMM operating speeds in PLL bypass mode are typically limited to 3000 MHz.
  • Single PLL mode: In the single PLL Mode, the clock buffer device will use a Phase Lock Loop (PLL) for the regeneration of the incoming host clock to create a better-quality clock that is sent to the DRAMs. However, since there is only one PLL that is used in this mode, both sub channel output clocks will be driven based on only one set of input clocks with the other set of input clocks remaining unused.
  • Dual PLL mode: In this mode, the clock buffer will use two PLLs to independently generate each sub channel output clock based on each set of incoming host clocks. The second set of PLL can be turned on or off on the fly if needed to save power.

Beyond the clock modes, clock buffers provide additional flexibility to the system designers with register-controlled additional signal delays, optional output clock enable/disable per bit feature, drive strength and termination choices, etc. All DDR5 clock buffer device control word registers are accessible via DDR5 DIMM sideband.

Cadence VIPs offers a compressive memory subsystem solution that includes memory models for DDR5 SDRAM, DDR5 RCD, DDR5 DB, DDR5 clock buffer, all types of DDR5 DIMMs, including the DDR5 CUDIMMs, DFI Memory Controller/PHY VIPs, and a system VIP compliant to JEDEC specifications defined for each of those devices along with latest DFI Specification.

More information on Cadence DDR5 DIMM VIP is available at the Cadence VIP Memory Models website.

AMS simvision cannot load big psf.trn

Hello all,

I have run a simulation with a lot of instnaces extraction and the psf.trn is >= 200 Gb, I tried to load it with simvision and it just breaks.

I would like to ask if there is a way to open this file, e.g. if I could read only some time window e.g. from 10us -> 15us.

getVersion(t)
"sub-version  ICADVM20.1-64b.500.34 "

XCELIUMMAIN23.03.001

thank you in advance

Jasper's elaborate -bbox_i seems to have no effect

I'm trying to use Jasper for checking parameter propagation in a large design. I have a list of top-level parameters, each with a HDL path of a module parameter somewhere lower in the hierarchy that's supposed to receive its value from the top-level module. The FPV app seems like an excellent tool for this, but elaborating the entire design in it is extremely time-consuming and memory-intensive. So, I'm trying to black-box everything but the interesting HDL paths. I thought using `elaborate -top dut_module_name -bbox_i * -no_bbox_i inst_foo -no_bbox_i inst_bar (...)` would work, but it doesn't. Jasper just starts flooding the log with warnings from modules that are definitely not on the whitebox list, and eventually dies due to insufficient memory. When I use -bbox_m * it correctly elaborates the top-level module with all of its sub-modules black-boxed. But then the -no_bbox_i switches have no effect. Could anyone suggest a working solution for this use case?

Creating cover items for sparse values/queue or define in specman

Hello,

I have a question I want to create a cover that consists a sparse values, pre-computed (a list or define) for example l = {1; 4; 7; 9; 2048; 700} I'd like to cover that data a (uint(bits:16)) had those values, Any suggestion on how to achieve this, I'd prefer to stay away from macros, and avoid to write a lot of code

struct inst {

  data :uint(bits:16);
  opcode :uint(bits:16);
  !valid_data : list of uint(bits:16) = {0; 12; 10; 700; 890; 293;};
  event data_e;
  event opcode_e;

  cover data_e is {
     item data using radix = HEX, ranges = {
     //I dont want to write all of this
     range([0], "My range1");
     range([10], "My range2");
     //... many values in between
    range([700], "My rangen");
    };


    item opcode;


   cross data, opcode;
};

post_generate() is also {
    emit data_e;
};
};
