IP-XACT can be useful in SystemC modeling.

EDA vendor IP-XACT tools are able to load IP-XACT XML documents and you can access the metadata in the internal databases of these tools using TGI without the need to do all the XML parsing yourself. Second, the standard provides a tool interface called TGI (Tight Generator Interface) that allows you to work with this metadata. The information in the XML documents adhering to these XML schemas is called metadata. The XML schemas also allow you to describe designs in terms of IP block instances and interconnect between these instances. First it provides XML schemas that allow you to describe IP blocks you can think of this as an electronic datasheet of an IP block. You can get a free copy of the standard using the link on. But what I really wanted was to define a better data structure (context API) for Jinja2 to consume.IP-XACT is an IEEE standard to enable IP reuse and to enable tool flows to easily work with IP. I made the template flexible enough by passing it on CLI. The last step is to write the templates to consume the context. Txt = block_template.render(context=block_context) Txt = reg_template.render(context=reg_context)īlock_template = self.jinja_env.get_template( 'reg_block.sv.jinja') Reg_template = self.jinja_env.get_template( 'reg.sv.jinja') Once I have that working, I can pass the contexts to Jinja to render. Reg_context.append(field_context)įield_context = field.find( 'ipxact:name', ns).textįield_context = field.find( Reg_context = reg.find(įor field in reg.findall( 'ipxact:field', ns): Reg_context = reg.find( 'ipxact:size', ns).text Reg_context = reg.find( 'ipxact:name', ns).text The UVM register layer classes are used to create a high-level, object-oriented model for memory-mapped registers and memories in a design under verification (DUV)īasically, Once fields and registers are defined, RAL provides a consistent access API for registers read/write.įor reg in addressBlock.findall( 'ipxact:register', ns):īlock_context.append(reg_context) Well, if you haven’t seen Register model before, I envy you. The important section is as it specifies the registers and fields.

IP-XACT is an XML format that defines and describes individual, re-usable electronic circuit designs (individual pieces of intellectual property, or IPs) to facilitate their use in creating integrated circuits (i.e. This was a weekend project back in 2020 to build IPXACT parser and UVM register Model generator.Īs an example of the lack of imagination at that time, I decided to call it ‘ipaxctral’.
