Exhibit 5.1

July 6, 2026

Silvaco Group, Inc.

4701 Patrick Henry Drive, Building #23

Santa Clara, CA 95054

Ladies and Gentlemen:

We have acted as New York

counsel to Silvaco Group, Inc., a corporation organized under the laws of Delaware (the “Company”), in connection with the

sale of up to 69,062 shares of common stock, par value $0.001 per share (the “Shares”). The Shares are included in a registration

statement on Form S-3 under the Securities Act of 1933, as amended (the “Securities Act”), filed with the Securities and Exchange

Commission (the “Commission”) on November 3, 2025 (Registration No. 333-291212) (the “Registration Statement”),

and are being offered pursuant to a base prospectus dated October 31, 2025 (the “Base Prospectus”) and a prospectus supplement

dated July 6, 2026 filed with the Commission pursuant to Rule 424(b) under the Securities Act (together with the Base Prospectus, the

“Prospectus”).

This opinion letter is rendered

in accordance with the requirements of Item 601(b)(5) of Regulation S-K under the Securities Act, and no opinion is expressed herein as

to any matter pertaining to the contents of the Registration Statement or related prospectus, any prospectus filed pursuant to Rule 424(b)

with respect thereto, other than as expressly stated herein with respect to the issuance of the Shares. In connection with our opinions

expressed below, we have examined originals or copies certified or otherwise identified to our satisfaction of the following documents

and such other documents, corporate records, certificates and other statements of government officials and corporate officers of the Company

as we deemed necessary for the purposes of the opinions set forth in this opinion letter:

(a) the Registration Statement;

(b) the Prospectus;

(the “Certificate of Incorporation”), filed as Exhibit 3.1 to the Company’s Current Report on Form 8-K filed with the

Commission on May 28, 2025;

(d) a copy of the Company’s Amended and Restated Bylaws

(the “Bylaws”), filed as Exhibit 3.2 to the Company’s Current Report on Form 8-K filed with the Commission on February

13, 2026; and

(e) a copy of the resolutions of the Company’s board of

directors adopted on January 2, 2026 and January 7, 2026.

We have relied, to the extent

we deem such reliance proper, upon such certificates or comparable documents of officers and representatives of the Company and of public

officials and upon statements and information furnished by officers and representatives of the Company with respect to the accuracy of

material factual matters contained therein which were not independently established by us. In rendering the opinions expressed below,

we have assumed, without independent investigation or verification of any kind, the genuineness of all signatures on documents we have

reviewed, the legal capacity and competency of all natural persons signing all such documents, the authenticity and completeness of all

documents submitted to us as originals, the conformity to authentic, complete original documents of all documents submitted to us as copies,

the truthfulness, completeness and correctness of all factual representations and statements contained in all documents we have reviewed,

the accuracy and completeness of all public records examined by us, and the accuracy of all statements in certificates of officers of

the Company that we reviewed. In addition, in rendering the opinions expressed below, we have assumed that the Shares will be executed

and countersigned by the transfer agent or registrar therefor as contemplated in the Registration Statement.

Based upon the foregoing assumptions

and the assumptions set forth below, and subject to the qualifications and limitations stated herein, having considered such questions

of law as we have deemed necessary as a basis for the opinions expressed below, we are of the opinion that the Shares, when sold and issued

against payment therefor in accordance with the Registration Statement and Prospectus, will be validly issued, fully paid and nonassessable.

The opinion expressed above

is limited to questions arising under the Delaware General Corporation Law. We do not express any opinion as to the laws of any other

jurisdiction.

This opinion letter is for

your benefit in connection with the Registration Statement and may be relied upon by you and by persons entitled to rely upon it pursuant

to the applicable provisions of the Securities Act. This opinion letter is provided solely in connection with the distribution of the

Shares pursuant to the Registration Statement and is not to be relied upon for any other purpose.

The opinion expressed above

is as of the date hereof only, and we express no opinion as to, and assume no responsibility for, the effect of any fact or circumstance

occurring, or of which we learn, subsequent to the date of this opinion letter, including, without limitation, legislative and other changes

in the law or changes in circumstances affecting any party. We assume no responsibility to update this opinion letter for, or to advise

you of, any such facts or circumstances of which we become aware, regardless of whether or not they affect the opinions expressed in this

opinion letter.

We hereby consent to the filing

of this opinion letter as Exhibit 5.1 to the Company’s Current Report on Form 8-K dated July 6, 2026 and its incorporation by reference

into the Registration Statement and to the reference to our firm as counsel for the Company under the caption “Legal Matters”

in the Prospectus. In giving this consent, we do not thereby admit that we are within the category of persons whose consent is required

under Section 7 of the Securities Act or the rules and regulations of the Commission thereunder.

Very truly yours,

/s/ White & Case LLP
