Transaction Level Modeling (TLM)

Blocking and Non-blocking Communication Using the TLI
Posted on Thursday, March 31, 2011 - 10:36 by John Aynsley from the site Verification Martial Arts
John Aynsley, CTO, Doulos In the previous blog post I introduced the VCS TLI Adapters for transaction-level communication between SystemVerilog and SystemC. Now let’s look at the various coding styles supported by the TLI Adapters, and at the same time review the various communication options available in VMM 1.2. We will start with the options for sending transactions from SystemVerilog to SystemC. VMM 1.2 allows transactions to be sent through the classic VMM channel or through the new-style TLM ports, which come in blocking- and non-blocking flavors.

VMM-to-SystemC Communication Using the TLI
Posted on Tuesday, March 22, 2011 - 13:12 by John Aynsley from the site Verification Martial Arts
John Aynsley, CTO, Doulos I have said several times on this blog that the presence of TLM-2.0 features in VMM 1.2 should ease the task of communicating between a SystemVerilog test bench and a SystemC reference model. Now, at last, let’s see how to do this – using the VCS TLI or Transaction Level Interface from Synopsys. The parts of the TLI in question are the VCS TLI Adapters between SystemVerilog and SystemC.

Accelerating Design Verification with Virtual CPU models

In today’s SOC architectures, one or more on-chip core(s) or CPU(s), like ARM or MIPS, are often used to provide flexibility in the system, through the use of embedded software. Besides executing software functionality, they program the hardware peripherals and perform I/O with them.

Blocking/Non-blocking Transport Adaption in VMM 1.2
Posted on Wednesday, September 1, 2010 - 19:20 by John Aynsley from the site Verification Martial Arts
John Aynsley, CTO, Doulos One neat feature of the SystemC TLM-2.0 standard is the ability provided by the so-called simple target socket to perform automatic adaption between the blocking and non-blocking transport calls; an initiator that calls b_transport can be connected to a target that implements nb_transport, and vice-versa. VMM 1.2 provides similar functionality using the vmm_connect utility. vmm_connect serves four distinct purposes in VMM 1.2.
