As Far as I understand Normal Chip is something that you design for a particular function. This undergoes testing and then finally goes into production.
On the other hand test chip is used to validate IPs, IO buffersand also get different parameters/values (like delay, resistance) etc for a...
getting orders for foundry
If you were to choose/select a foundry for a particular project what prameters would you look at?
More from a technical point of view than cost?
If you have a post-synthesis SDF you can load the design netlist and SDF in Primetime, give appropriate constraints for Clock,IO and exceptions, Set operating conditions and then you can use report_timing to get the timing information
Hi
I am trying to run Magma Blast Fusion on Mandrake 10.1. When I try to start GUI it gives error "Failed to Start wathcer process" UI-39. NSCD daemon is running. Has anyone faced similar problem.
mux netliste
RTL : Functionality of device written in language like Verilog, VHDL. Its called RTL if it can be synthesized that is it can be converted to gate level description.
Netlist: You get a netlist after you synthesize a RTL. This is gate level description of the device. The high level...
Re: ECO cells
If you mean spare cells, then these cells are strategically placed in layout but are not a part of any functional circuit. i.e they are not connected. These are used in case a respin is required ie some minor changes in layout is required to bug fix.
By using spare cells you can...
Re: tapeout
Tapeout means all the design stages is complete i.e RTL Design, synthesis, Layout DRC, LVS and the design is ready to be fabricated. Let me know if this clarifies.
SDF stands for Standard Delay Format. This file contains delay information. For eg:
1. For combinational gates : The prop delay from change in input to change in output.
2. Sequential Cell: Clock-2-Out delays.
3. And also interconnect delays.
After Layout, parasitic-extraction is done. The...
calibre xrc res2
I faced similar problem. The extraction was taking too long almost 24 hrs and was getting killed after that. The problem is that once RAM is utilized it starts putting data on VM (HDD) and that takes too long. We had to increase VM and also by upgrading to newer version we saw...
Re: Regarding Filler Cells
IN standard cells APR flow:
the cells in the design are placed on the row. To make sure that
each cells gets power and ground connection, the cells are abutted
together so that the VDD and VSS terminal of neighbouring cells
short together. This makes it possible to...
Re: Regarding Filler Cells
when performing automatic place and route using standard cells there will be discontinuity in power,ground and diffusion layers because all the cells will not be abutting. Fillers cells are inserted in between to get the continuity back.
hope this helps.
